We specialize in manufacturing titanium anodes and have been serving various electrochemical industries with high-performance, long-lasting titanium electrode products for years. Based on our extensive production experience, we’ve outlined the key surface pre-treatment processes and steps for “coated titanium anodes before applying and sintering precious metals.”
The first four pre-treatment steps determine the adhesion, uniformity, and durability of the subsequent precious metal coating. Below, we explain each step’s principles and key points.
Remove Oil and Particles
Rinse and Dry
Goal: Ensure the titanium substrate is free from oil and particles, creating a clean base for mechanical or chemical roughening.
Mechanical Grinding
Sandblasting
Goal: Achieve a suitably rough surface to ensure the precious metal slurry “grips” the substrate at a microscopic level, enhancing coating adhesion and durability.
2. Soaking and Process Control
3. Neutralization and Rinsing
Goal: Deeply clean oxidation layers and hidden contaminants, activating the titanium surface for a strong bond with the precious metal coating.
Drying
Visual and Roughness Inspection
Cleanliness Testing (Optional)
Goal: Guarantee each titanium substrate meets roughness and cleanliness standards before applying the precious metal coating.
Our extensive experience in titanium anode production shows that every successful precious metal coating starts with robust surface pre-treatment. Properly following the “Cleaning/Degreasing → Roughening → Acid Activation → Drying/Inspection” process improves coating adhesion, corrosion resistance, and product lifespan.
If you have any questions about titanium anode production or surface pre-treatment techniques, feel free to reach out. We look forward to collaborating with you to deliver high-quality, long-lasting titanium anode products that offer stable and reliable performance for your applications.
In titanium anode manufacturing, surface pre-treatment is the foundation for successful precious metal coating. Poor or excessive pre-treatment can cause major issues in the coating process, leading to quality failures and financial losses. At Ehisen, we ensure every step of pre-treatment is precise to guarantee high-quality results.
| Problem | Cause | Effect on Coating | Impact on Performance |
|---|---|---|---|
| Incomplete Cleaning | Residual oil, dirt, or dust on the titanium surface | Weak adhesion, causing the coating to peel | Reduced durability and faster corrosion |
| Uneven Sandblasting | Inconsistent roughness or insufficient roughening | Uneven coating thickness, weak mechanical bonding | Coating detachment, lower efficiency |
| Excessive Sandblasting | Overly rough surface due to high pressure or grit size | Poor coating uniformity, localized thickness issues | Stress concentration, shorter product lifespan |
| Under-Acid Washing | Residual oxidation or contaminants | Poor adhesion, bubbles, or layer separation | Lower durability, early failure |
| Excessive Acid Washing | Overly dissolved surface, thinner substrate | Weak bonding, reduced mechanical strength | Cracks or failure under load |
| Insufficient Drying | Moisture left on the surface | Bubbles and uneven coating | Adhesion problems, increased risk of peeling |
| Lack of Inspection | No checks for cleanliness, roughness, or defects | Undetected surface flaws lead to inconsistent quality | Unstable performance and unpredictable results |
Overly Rough Surfaces
Excessive sandblasting creates highly rough surfaces. While it improves bonding strength, it makes it difficult to achieve an even coating, leading to areas with uneven thickness. This reduces the overall lifespan of the titanium anode.
Reduced Structural Integrity
Excessive acid washing can thin the substrate, compromising its mechanical strength and making it prone to cracking during use.
Increased Coating Defects
Overly aggressive pre-treatment may introduce stress points or defects in the surface, causing bubbles or cracks in the final coating.
Controlled Surface Roughness
At Ehisen, we balance adhesion and coating uniformity by precisely controlling sandblasting parameters, ensuring optimal roughness (Ra values).
Comprehensive Inspections
Every titanium substrate undergoes rigorous checks for cleanliness, roughness, and uniformity before moving to the coating stage. Any issues are resolved to prevent defects later.
Batch Confirmation Before Coating
We ensure that all pre-treatment steps meet standards before starting the precious metal coating process, avoiding costly post-coating failures.
Detailed Process Records
We maintain full records of each step, including cleaning, sandblasting, acid washing, and drying, for complete traceability and transparency.
Collaborative Testing
Ehisen works with clients to simulate real-world applications and verify product quality, reducing risks and ensuring consistency.
