Composite Coatings
- Layering different coatings or metal oxides (e.g., Pt first, then Ru-Ir) may combine multiple benefits.
- Usually requires custom solutions and upfront testing by specialized manufacturers.
5.From Requirements to Coating Content
5.1. Provide Clear Process Information
- Operating Environment: Specify the electrolyte type (chloride, sulfuric acid, seawater, etc.), operating temperature, and pH range.
- Working Current Density: Estimate or provide typical current densities (e.g., 5 A/dm², 10 A/dm²).
- Operating Time & Lifetime Needs: Will the anode run 8 hours a day or 24/7? Is the planned service life 1 year, 3 years, or longer?
- Industry & Production Scale: Different industries have varying demands for anode lifespan, process stability, and safety. Production volume also affects raw material costs and ROI.
5.2. How Suppliers Convert Your Information into “Precious Metal Usage”
- Matching Electrochemical Parameters: Based on current density and corrosiveness of the solution, suppliers estimate how many grams of precious metals (Ir, Ru, Pt, etc.) or what coating thickness is needed.
- Balancing Lifetime & Cost: For high current density in highly corrosive environments, a higher ratio of precious metals (Ir or Pt) is often required, raising costs but extending anode life.
- Coating Technology: Each supplier’s process differs. The same amount of precious metal can yield different catalytic activity and durability depending on the manufacturing method.
5.3. Why This Matters to Buyers
- Evaluating Price Differences: Each supplier’s choice of Ru, Ir, Pt, or MMO coatings—and how many grams of precious metals are used—directly affects the quote.
- Understanding Investment & Return: If the precious metal content is too low, the anode may fail prematurely; too high and initial costs soar. Finding the right balance is key.
- Ensuring Production Stability: In tough environments (e.g., highly oxidative solutions or high temperatures), insufficient precious metal content can lead to higher maintenance and downtime costs than any initial savings.
5.4. Communicating Coating Requirements Effectively
- Share Detailed Process Data: Include specifics like chemical composition, temperature, flow rate, pH, and production targets.
- Compare Multiple Suppliers: Request lab-based accelerated life tests, real-world case studies, or third-party validation.
- Consider Maintenance & Replacement Costs: Think about total cost of ownership (TCO) instead of just the initial purchase price. Factor in anode lifespan and operational efficiency.
5.5. Key Takeaways
- By understanding how precious metal grams and coating formulas vary with different operating conditions, you can better judge supplier quotes and technical proposals.
- A sensible investment in the right coating can reduce downtime, maintenance, and electricity consumption, maximizing the value of your titanium anodes.
Conclusion
By understanding how precious metal coatings work—how many grams are needed, the right coating thickness, and how to balance cost and performance—you’ll be in a much better position to communicate your specific requirements. From our standpoint as a supplier, this clarity greatly streamlines collaboration. The more precisely you can describe your process environment and goals, the easier it is for us to recommend an optimal coating solution.
If you’d like to test your operating conditions first, Ehisen can provide titanium anode samples for trial runs.

Common Precious Metal Coating Ratios & Their Impact on Service Life
1. Typical Market Ratios
The table below shows standard coating systems along with usual ratios or thicknesses. Actual values may vary due to anode shape, operating conditions, and required current density.
| Coating System | Typical Ratios / Thickness / Loading | Main Uses & Features | Advantages | Limitations / Notes |
|---|---|---|---|---|
| Ru-Ir System | – Common ratios: 8:2, 7:3, 6:4 (by mole or weight) – About 5–15 g of metal/m², adjustable to needs | – Used in chlor-alkali, electroplating, wastewater treatment – Good for chlorine evolution, corrosion-resistant, combines Ru’s high activity with Ir’s stability | – More balanced cost & performance than single Ru or Ir – Longer service life vs. pure Ru | – Higher Ir content raises cost – Needs careful assessment under strong oxidation or very high current |
| Ir-Ta System | – Ir content often around 5–18 g/m² (adjusted for corrosion/lifespan) – Ratios like 70% Ir : 30% Ta possible | – Common in electrochemical oxidation, ozone generation, strong acid environments – Exceptional corrosion resistance, especially in highly acidic, oxidizing media | – Longer service life – Handles high current densities with good stability | – Ir price fluctuates, so total cost can be high – Insufficient Ta content may reduce corrosion resistance |
| Pt-Based System | – Plating thickness usually 0.5–10 μm – Or by weight (e.g., 5–20 g Pt/m²) but must balance substrate vs. coating to ensure good adhesion | – Used in harsh or high-purity settings (pharma, fine chemicals, electroanalysis) – Pt is highly inert, offers excellent corrosion resistance and conductivity | – Superb corrosion resistance and conductivity – Ideal for ultra-pure applications | – Pt is expensive – Excessive thickness can raise costs sharply; poor substrate adhesion lowers performance |
Note: These figures are broad guidelines. Actual ratios and thicknesses depend on factors like electrolyte chemistry, temperature, pH, operating hours, and production needs.
2. The Role of Additives in Precious Metal Coatings
Types of Additives
- Metal Doping: Elements like Pd, Ta, Sb can enhance catalytic activity or corrosion resistance.
- Stabilizers: Help maintain coating integrity in high-temperature or strongly oxidative settings, reducing metal loss.
- Dispersants: Ensure metal particles spread evenly on the surface, improving adhesion and density.
Impact Range

- Cost: Usually used in small amounts, but rare or exotic additives can drive up expenses. Evaluate cost vs. performance gain.
Points to Consider
- Side Reactions: Some additives may cause passivation or unwanted by-products under certain conditions.
- Pre-Testing: Lab-scale or accelerated aging tests are advised to ensure additives work as intended in real conditions.
3. Real-World Use: Composite Coatings & Case Study
Principles of Composite Coatings
- Applying multiple layers or mixing various metals (e.g., Pt base for high conductivity + Ir-Ta for corrosion resistance) to achieve superior overall performance.
- Suitable for demanding electrochemical applications with complex operating conditions.
Case Study: EDI Titanium Anode with Composite Coating
- Background: A customer sought to increase conductivity by first plating a thin Pt layer on titanium, then adding an Ir-Ta coating.
- Issue: In actual use, chlorine gas produced by the anode ended up damaging the water purification membrane, reducing EDI efficiency.
- Analysis: While conductivity improved, the potential chlorination effect on membranes was overlooked. This highlights that “more metals” doesn’t automatically mean “better”—the entire process, including by-products and compatibility with components like membranes, must be evaluated.
Practical Tips
- Thorough lab simulation or pilot testing is crucial before deciding on composite coatings to avoid unexpected field issues.
- For membrane-based or high-purity processes, always check for chemical or physical damage from by-products like chlorine.
4. Key Steps to Choosing the Best Coating Ratio
- Clarify Operating Conditions & Goals: Know your electrolyte type, temperature, pH, current density, and required anode lifespan.
- Balance Cost vs. Maintenance: Consider upfront investment vs. how often the anode might need servicing, and potential downtime costs.
- Collaborate with Experienced Suppliers: They usually have proven test data and real-world examples to guide you to the right metal loading.
- Pilot Testing & Accelerated Aging: Validate coating performance in lab or small-scale runs to confirm it meets your requirements.
- Stay Flexible: As metal prices or production demands change, you may need to adapt the coating formula to maintain the best cost-performance ratio.
Summary
Different coating systems—Ru-Ir, Ir-Ta, Pt-based, or composites—excel in different scenarios. The real-life lifespan of a titanium anode depends not only on precious metal loading or thickness but also on how well the coating suits your actual working environment. By thoroughly communicating with a knowledgeable supplier, running small-scale tests, and reviewing performance data, you can select the ideal coating formula that strikes a balance between optimal performance and overall cost-effectiveness.
Precious Metal Ratios, Cost Control & Economic Benefits

- With a consistent manufacturing process, the amount (in grams) of precious metal used can be clearly calculated, giving buyers a direct way to assess cost.
Reference Note: According to industry journals (e.g., Electrochemical and Solid-State Letters), prices for Ru, Ir, and Pt have varied widely over the last decade. Both suppliers and buyers should keep an eye on market trends to plan more flexible quotes and purchases.
2. Balancing Performance & Economics: Choosing the Right Metal Concentration
The Risk of Over-Concentrating
- Simply adding more precious metal dramatically increases the initial purchase cost. If your process doesn’t truly need such high-grade durability or efficiency, it could be wasted money.
- For instance, adding too much iridium to an Ir-Ta system may not yield a proportional increase in lifespan, so practical checks are essential.
The Hidden Costs of Under-Concentrating
- Trying to cut costs by drastically lowering metal loading can shorten the anode’s lifespan, requiring frequent replacements or downtime.
- Lower electrochemical efficiency also means higher energy consumption and increased overall operating expenses.
Theory + Practice
- Theoretical calculations give a starting point for metal ratios, but real-world factors (pH, temperature, solution chemistry) differ from plant to plant.
- Most suppliers advise starting with a slightly higher metal load for safer performance, then fine-tuning after practical usage feedback.
3. How Our Approach Adapts to Different Client Priorities
Clients Focused on Price
- With a limited budget, we propose a “minimum viable” metal loading for initial testing.

By referring to standard industry ratios, buyers can quickly identify the most suitable supplier and solution for their processes.Risk Avoidance:
Knowing the failure limits of different ratios (e.g., Ru-based coatings in chlor-alkali applications degrade 80% when pH >5) helps reduce trial and error risks.
Precise Control of Solution Physicochemical Parameters
In the process of preparing precious metal solutions, controlling physicochemical parameters like the concentration of metal salts and the pH value is crucial to ensuring the quality of the titanium anode coating. These parameters not only directly affect the coating’s formation rate and quality but also play a significant role in the anode’s lifespan and cost management. Therefore, precise control of these parameters is essential for enhancing anode performance and keeping production costs reasonable.
1. Gradient Management of Concentration
The concentration of precious metal salts (such as RuCl₃) is one of the key factors influencing coating quality. The recommended concentration range is 0.2-0.5 mol/L. If the concentration is too high or too low, it can cause coating issues, which, in turn, affect the anode’s lifespan and production cost.
Impact of High Concentration
When the concentration of precious metal salts is too high, cracks and surface unevenness may appear in the coating. This not only reduces the mechanical strength of the coating but also affects its electro-catalytic performance, leading to a shorter anode lifespan. Thicker coatings may also lead to material waste and higher production costs. Therefore, precise concentration control ensures an even coating and helps manage production costs.Impact of Low Concentration
On the other hand, if the concentration of the metal salts is too low, the coating may become thin and uneven. This reduces the electro-catalytic activity and corrosion resistance of the anode. A thinner coating may not provide sufficient current density support and can cause early failure of the anode, leading to frequent replacements and higher long-term operational costs.
By accurately managing the solution concentration, manufacturers can maintain coating quality while minimizing material waste, extending product lifespan, and effectively reducing overall production costs.
2. Dynamic pH Balance
Controlling the pH value is critical to the stability and quality of titanium anode coatings. Different pH levels significantly affect the solubility of metal salts, deposition rate, and coating quality. Improper pH values can affect the coating’s formation and directly impact the anode’s durability and cost.
Benefits of Acidic Environment (pH 1-3)
In acidic environments, Ru-based solutions (such as RuCl₃) are more stable and can form a uniform, stable coating more quickly. This environment helps control the coating deposition rate, avoiding thick or uneven layers and ensuring a longer anode lifespan. Since stable coatings help prevent wear and corrosion, they reduce the frequency of anode replacement, ultimately lowering long-term maintenance costs.Challenges of Alkaline Environment (pH 10-12)
In an alkaline environment, Ru and other precious metal salts are less stable and prone to oxide precipitation. To prevent this, complexing agents must be added to stabilize the metal salts. However, using complexing agents increases production costs. Poor pH control in alkaline conditions can result in unstable coatings, excessive thickness, and reduced electro-catalytic efficiency, all of which affect the anode’s performance and longevity.
3. Synergistic Effect of Concentration and pH
There is a close relationship between the concentration of precious metal salts and the pH value in the solution. Optimizing both parameters can significantly improve the performance and cost-effectiveness of titanium anodes. Only when both concentration and pH are correctly adjusted can the coatings achieve the best electro-catalytic activity and stability, thus extending the anode’s lifespan.
- Optimizing pH and Concentration Together
By ensuring the proper concentration of metal salts and dynamically adjusting the pH, manufacturers can achieve high-quality coatings. If either of these parameters is off, it could lead to uneven coatings or poor adhesion, ultimately shortening the anode’s lifespan. An ideal combination of concentration and pH minimizes both the production cost and the risk of quality issues.
4. Challenges of Precise Physicochemical Control and Cost Optimization
In actual production, controlling solution parameters precisely can be challenging. Even small fluctuations in concentration and pH can impact the coating quality and lead to performance degradation. Therefore, manufacturers must invest in high-precision equipment and automated control systems to monitor and adjust these parameters in real-time.
However, the investment in precise control has significant returns. By controlling physicochemical parameters precisely, manufacturers can improve product quality, extend the lifespan of titanium anodes, and reduce maintenance frequency, ultimately lowering the total cost of ownership (TCO). In a competitive market, extending the product lifespan and controlling production costs are essential strategies for improving product competitiveness.
Summary
The precise control of solution physicochemical parameters is not only important for the formation rate and quality of titanium anode coatings but also directly related to the anode’s lifespan and production costs. By optimizing the concentration of precious metal salts and the pH value, manufacturers can ensure stable coatings with excellent electro-catalytic performance and extended lifespan. This precision control ultimately reduces long-term costs, providing a competitive edge in the market.
How Process Parameters Affect Coating Performance
Why Are Process Parameters Like the “Cooking Time”? — A Simple Understanding of Thermal Decomposition Method
Think about baking a cake: if the temperature is too high, the cake burns; if it’s too low, it won’t set properly. The process of preparing titanium anode coatings using the thermal decomposition method works similarly. High temperatures “bake” the precious metal solution into a dense, durable coating.
- Key Steps:
- Apply precious metal solution → High-temperature sintering → Form an oxide layer.
- Core Goal:
- Ensure the coating grows evenly on the titanium base, without cracking, peeling, and with good conductivity!
Temperature Control: The “Golden Cooking Time” for Coatings
Different coating materials require different sintering temperatures, just like how various ingredients need different cooking temperatures:
| Coating Type | Ideal Temperature Range | Effects of Too Low Temperature | Risks of Too High Temperature |
|---|---|---|---|
| Ruthenium-Based Coating (e.g., Chlor-Alkali Anodes) | 400-500°C | Loose coating, easily peels off (like uncooked batter) | Surface cracks, conductivity decreases (like burnt cookies) |
| Iridium-Based Coating (e.g., Electroplating Anodes) | 550-600°C | Insufficient catalytic activity, higher energy consumption (motor “struggling”) | Precious metal oxidation failure, lifespan reduced by over 50% |
Buyer Value:
- Determine Reasonable Price: High-temperature sintering equipment costs more (e.g., equipment for 600°C is 30% more expensive than 500°C), but it produces more durable iridium-based coatings.
- Quality Verification Tip: Ask the supplier to provide scanning electron microscope (SEM) images of the coating. A properly controlled coating surface should look like “smooth ceramic,” not “cracked earth.”
Stirring Technology: The “Secret Weapon” for Coating Uniformity
The way the precious metal solution is mixed directly affects the coating quality. Here are two common stirring methods:
| Stirring Method | Analogy | Coating Effect | Cost Impact |
|---|---|---|---|
| Magnetic Stirring | Like stirring sugar water with a spoon | Generally even, but may have some “clumps” (ion aggregation) | Lower cost, suitable for standard needs |
| Ultrasonic Dispersion | Like using a blender for juice | Extremely uniform, coating porosity <3% (virtually defect-free) | Higher equipment investment, prices 10-15% higher |
Buyer Decision Recommendations:
- Choose Based on Need: If your process current density is <2000A/m², magnetic stirring coatings are sufficient. For high-end PCB electroplating (current density >5000A/m²), ultrasonic dispersion is recommended.
- Avoid Pitfalls: If a supplier claims “low-cost, high-quality ultrasonic coatings,” be cautious—they may be misrepresenting the process!
How to Judge Cost-Effectiveness Based on Process Parameters
Check Temperature and Coating Matching
Example: If purchasing iridium-based coatings, and the supplier uses a sintering process below 550°C, they may be sacrificing coating lifespan to reduce costs.Ask About Stirring Technology
Request a coating porosity report (high-quality coatings should have porosity <5%).Calculate Total Cost
High-temperature + ultrasonic processes make anode prices 20% higher, but if the lifespan is extended by 50%, it is more cost-effective in the long run.
Buyer Action Checklist
✅ Must-Ask Questions:
- “What is the sintering temperature for this iridium-based coating? Can you provide temperature curve records?”
- “Is the coating made with magnetic stirring or ultrasonic dispersion? What is the porosity detection result?”
✅ Pitfall Guide:
- Be wary of “ultra-low-cost iridium coatings”—they might be poorly sintered at low temperatures with insufficient iridium content!
- Ask for third-party test reports: Focus on “coating adhesion strength (should be >15MPa)” and “porosity.
How This Knowledge Helps Buyers
By understanding how temperature and stirring techniques affect the coating process, buyers can:
- Evaluate Price vs. Quality: Recognize when a supplier might be offering a lower price by cutting corners in the coating process, leading to poor-quality products.
- Identify High-Quality Products: Look for suppliers that use the right temperature ranges and advanced mixing techniques, which ensure a more durable and effective coating.
- Make Informed Decisions: Understand that certain process parameters directly impact the lifespan of the titanium anode, which can save money in the long run by reducing maintenance and replacement costs.
In short, learning about these key process parameters gives buyers the tools they need to evaluate the value of the products they’re considering, ensuring they make the best investment for their needs.
The Key Impact of Additives on Titanium Anode Lifespan
Types of Additives in the Industry and Their Functions
In titanium anode production, additives directly affect lifespan by improving the coating structure and enhancing the bonding between the coating and the titanium base. Below is a comparison of the most common additive solutions used in the market:
| Additive Type | Representative Substance | Core Function | Typical Lifespan Increase |
|---|---|---|---|
| Fluorides | NH₄F, NaF | Activates the titanium surface, improves coating adhesion | +30%~50% |
| Surfactants | OP-10, Sodium Lauryl Sulfate | Reduces surface tension, improves coating uniformity | +20%~35% |
| Chelating Agents | EDTA | Stabilizes precious metal ions, prevents local aggregation | +25%~40% |
| Inorganic Acid Inhibitors | Tartaric Acid, Oxalic Acid | Slows down excessive corrosion of titanium base, protects microstructure | +15%~30% |
Additive Function Breakdown
Fluorides: The “Strong Glue” Between Coating and Base
- Mechanism:
Fluoride ions (F⁻) corrode the surface of the titanium, creating a rough microstructure. This increases the coating’s contact area (5-8 times more than a smooth surface).
The surface passivation layer is removed, allowing precious metal oxides to securely anchor to the titanium base. - Lifespan Comparison:
In chlor-alkali electrolysis:- Without fluoride additives: Coating lifespan of about 8,000 hours.
- Adding 0.5% NH₄F: Lifespan extends to 12,000 hours (adhesion strength increases from 12 MPa to 18 MPa).
- Mechanism:
Surfactants: The “Smooth Master” for Coatings
- Mechanism:
Surfactants reduce the surface tension of the solution, allowing precious metal ions to spread evenly (contact angle decreases from 75° to 35°).
They also help reduce stress cracks that can form during the coating’s drying process. - Industry Application Example:
A PCB electroplating factory test:- Without surfactants: Coating porosity of 8.2%, average lifespan of 4,500 hours.
- Adding 0.1% OP-10: Coating porosity of 3.7%, average lifespan of 6,200 hours.
- Mechanism:
Chelating Agents: “The Order Keeper” for Precious Metal Ions
- Mechanism:
Chelating agents like EDTA form stable complexes with ions like Ir³+ and Ru³+, preventing hydrolysis reactions and extending the solution’s effective life (2x longer).
They help avoid local concentration build-up that causes uneven coating. - Failure Warning:
Low-quality suppliers often overuse chelating agents (>5%), which can prolong the solution’s shelf life but lead to carbonized black spots on the coating, ultimately reducing lifespan.
- Mechanism:
Buyer Value Points
Cost-Effectiveness Evaluation:
High-quality additive solutions can extend the anode lifespan by over 30%, reducing the overall purchase cost by ¥8,000–12,000 per anode (based on a unit price of ¥30,000).Supplier Technology Identification:
- Basic Suppliers: Only use one additive (e.g., just fluoride), resulting in a lifespan increase of <25%.
- Premium Suppliers: Use a composite of additives (e.g., fluoride + surfactant + chelating agent), achieving lifespan increases >40%.
Testing Validation Methods:
- Ask for SEM images of the coating cross-section: High-quality coatings should show a continuous gradient structure (from base → transition layer → functional layer).
- Request accelerated lifespan test reports: At a 2A/cm² current density, a qualified product should last ≥600 hours (equivalent to an actual lifespan of approximately 8,000 hours).
Industry Real-World Data Reference
| Application Scenario | Best Additive Combination | Measured Lifespan (hours) | Competitor’s Typical Lifespan |
|---|---|---|---|
| Chlor-Alkali Electrolysis (32% NaOH) | 0.3% NH₄F + 0.05% OP-10 | 15,200 | 9,800 |
| Nickel Plating (pH=4.2) | 0.2% EDTA + 1% Tartaric Acid | 8,700 | 5,400 |
| Aluminum Foil Anodizing (Ethylene Glycol) | 0.5% NaF + 0.1% Sodium Lauryl Sulfate | 11,500 | 7,200 |
Supplier Capability Assessment Guide
✅ Technical Strength Inquiry Checklist:
- “Has your additive formula been optimized through orthogonal experiments? Can you provide lifespan comparison data for different combinations?”
- “Can you adjust additive compatibility based on our electrolyte composition (e.g., containing F⁻ or organic materials)?”
- “What standard do you use to measure coating and substrate adhesion (e.g., ASTM D4541 or GB/T 5210)?”
✅ Risk Avoidance Tips:
- Be cautious of suppliers who claim “confidential additive formulas” but cannot provide test reports.
- Prefer suppliers who disclose the basic types of additives used (e.g., fluoride/chelating agents) and provide performance guarantees.
