Platinum Plated Titanium Anode Project

We undertook a project to supply platinum plated titanium anodes for UK plate making equipment. First, we evaluated the drawings, considering substrate dimensions, machining processes, and tooling design. After the customer confirmed our offer, we produced and assembled the parts, then applied the platinum plating. Finally, we measured the sizes, checked the coating condition, and packaged everything for shipment.

The titanium electrodes FAQ

What industries are ruthenium-iridium titanium anodes used in?
  1. Chlor-alkali industry: To produce chlorine and caustic soda by saltwater electrolysis.
  2. Electroplating: For surface treatment and coating metals.
  3. Seawater desalination: Used in processes like electrodialysis and reverse osmosis.
  4. Water treatment: For wastewater purification and electrochemical oxidation.
  5. Cathodic protection: To prevent metal structures from corrosion.
  6. Organic and electrochemical synthesis: For producing specific organic compounds.

1. Excellent Catalytic Performance

  • Chlorine Evolution Reaction (Cl₂): In the chlor-alkali process, the main reaction at the anode is:

    2Cl−→Cl2(g)+2e−

    Ruthenium-iridium coatings have low overpotential and high efficiency for chlorine generation.

  • Oxygen Evolution Reaction (O₂): In water treatment and electroplating, the anode reaction is often:

    2H2O→O2(g)+4H++4e−

    The coating is also effective at catalyzing oxygen generation.

2. Corrosion Resistance

  • Ruthenium and iridium are noble metals that resist corrosion, even in harsh environments with strong acids, bases, or chlorine.

3. Long Service Life

  • The coating bonds well to the titanium base and doesn’t peel off easily, ensuring a long lifespan and reducing maintenance costs.
  • Ruthenium (Ru): Excellent for chlorine evolution (Cl₂), used in chlor-alkali and chloride-rich environments.
  • Iridium (Ir): Great for oxygen evolution (O₂), used in water treatment and plating processes.
  • Ratio matters: Adjusting the Ru-Ir ratio changes the anode’s catalytic performance, corrosion resistance, and cost.

1. Check Materials and Coating Specifications
Base Material: Ensure the anode uses pure industrial titanium, like Gr1 or Gr2, for its corrosion resistance and strength.
Coating Ratio: Ask for the Ru/Ir ratio (e.g., 70:30 or 50:50) and coating thickness (usually 5-10 microns).
Test Reports: Request material composition and coating analysis, such as spectrometry results.
2. Test Product Performance
Electrochemical Testing:
Ask for performance reports showing:
Chlorine evolution potential (Cl₂)
Oxygen evolution potential (O₂)
Durability tests (e.g., accelerated lifespan testing)
Check efficiency and stability under your application conditions.
Corrosion Resistance:
Review tests showing the coating’s resistance in harsh environments, such as acidic, alkaline, or chloride-rich solutions.

      2. Compare the readings with the design values or operating parameters to ensure the current is within the expected range.
    • Frequency:
      1. Inspect every quarter or half-year, especially in high-current environments.
    • Note:
      1. If the current is too low, it could indicate power supply issues, coating damage, or increased electrolyte resistance.

    Method 2: Potential Testing

    • Steps:
      1. Measure the potential difference between the protected structure and a reference electrode (e.g., Cu/CuSO₄ electrode).
      2. Confirm that the protected structure remains within the safe potential range (e.g., below -850 mV for steel structures).
    • Purpose:
      • Indirectly evaluate the current distribution and performance of the anode.

    Method 3: Voltage Drop Test

    • Steps:
      1. Measure the voltage drop at the anode connection points.
      2. If the voltage drop is too high, it could indicate corrosion or increased resistance in cables or connections.

    2. Checking Coating Wear

    Method 1: Visual Inspection

    • Steps:
      1. Remove the anode and visually check for signs of coating peeling, discoloration, or cracks.
      2. Compare the current condition with the original state to assess physical wear.
    • Frequency:
      • Inspect annually or every two years, especially in harsh environments like high salinity or acidic conditions.

    Method 2: Coating Thickness Measurement

    • Steps:
      1. Use an X-Ray Fluorescence (XRF) deviceto measure the coating thickness.
      2. Compare with the initial coating thickness to evaluate the wear rate.
    • Purpose:
      • Accurately detect remaining coating thickness and predict anode lifespan.

    Method 3: Resistance Testing

    • Steps:
      1. Test the surface resistance or overall conductivity of the anode.
      2. A significant increase in resistance may indicate coating damage or decreased uniformity.

    Method 4: Electrochemical Performance Testing

    • Steps:
      1. Place the anode in a simulated electrolyte and measure overpotential and current efficiency.
      2. Assess the anode’s performance under working conditions.

The titanium electrodes FAQ

What are the models and specifications of sodium hypochlorite generators?

1. By Chlorine Production Capacity

  • Small-scale Units:
    • Chlorine Output: 5g/h – 100g/h.
    • Applications: Small swimming pools, household water disinfection, and small water treatment projects.
  • Medium-scale Units:
    • Chlorine Output: 100g/h – 10kg/h.
    • Applications: Public swimming pools, hotels, hospitals, and community water stations.
  • Large-scale Units:
    • Chlorine Output: Over 10kg/h.
    • Applications: Industrial water treatment, large-scale water plants, and municipal water supply systems.

1. Suitable Water Sources

  • Tap Water:
    • The most common water source due to its stable quality and easy availability.
    • Tap water is usually pre-treated with fewer impurities, making it ideal for the equipment.
  • Groundwater:
    • Can be used, but proper pre-treatment is necessary to remove impurities and hardness.
    • In some regions, groundwater may contain high hardness or iron and manganese ions, which could affect performance.

2. Water Quality Requirements

  • TDS (Total Dissolved Solids):
    • The total dissolved solids content should be below 200mg/L to prevent scaling on the electrodes.
  • Hardness:
    • Water hardness should be less than 120mg/L (as CaCO₃) to reduce calcium and magnesium deposits.
  • Impurities:
    • Suspended particles, sand, and other impurities must be removed. A filter is recommended for pre-treatment.
  • Heavy Metal Ions:
    • Avoid water with high concentrations of iron, manganese, or other heavy metal ions.
  • Chloride Ions:
    • Adequate chloride ion levels (usually maintained by dissolving salt) are required to ensure electrolysis efficiency.

1. Operating Costs

  • Sodium Hypochlorite Generators:
    • Use salt and electricity as raw materials, making operating costs relatively low.
    • Ideal for large-scale applications, with unit disinfection costs decreasing as production scales up.
  • Traditional Disinfection Methods:
    • Use liquid chlorine or bleach powder, with lower initial procurement costs but higher transportation and storage expenses.
    • Long-term use increases total costs due to continuous chemical purchases.
