Platinum Plated Anodes: Premium Solutions for Metal Finishing

PurePlat™ platinum coating is 99.95% pure platinum coating applied typically by electrodeposition to Titanium, Niobium, Tantalum and other exotic substrates. The electrodeposited or clad-coated substrate is more cost-effective and mechanically superior to pure platinum structures. We ensure optimum performance of the PurePlat™ coating by varying the surface morphology to create an application- and process-specific electrochemical characteristic.

Applications include: precious metal plating, electrolytic recovery, cathodic protection, electrophoresis, electrochlorination, electrosynthesis of organic and inorganic compounds, electrodialysis, electrodionization, electrochemical oxidation and/or reduction, and more.

BENEFITS OF PLATINUM PLATED ANODES

  • Exceptional Conductivity:
    Platinum is renowned for its excellent electrical conductivity, which ensures efficient and uniform current distribution. This is crucial for achieving consistent, high-quality coatings in electroplating and other electrochemical processes.

  • Superior Corrosion Resistance:
    Platinum’s resistance to corrosion and oxidation in a wide range of chemical environments makes platinum plated anodes ideal for use in harsh conditions. This durability extends the lifespan of the anodes, reducing the frequency of replacements and maintenance.

  • High Stability and Longevity:
    The robustness of platinum plating ensures that the anodes maintain their integrity and performance over long periods, even under high-stress conditions. This longevity translates to lower long-term operational costs and reliable production quality.
  • Low Maintenance:
    Due to their durability and resistance to corrosion, platinum-plated anodes require minimal maintenance compared to other types of anodes.

  • Enhanced Efficiency:
    Platinum plated anodes operate at lower overpotentials, which means they require less energy to drive electrochemical reactions. This efficiency not only reduces power consumption but also improves the overall sustainability of metal finishing processes.

  • Minimal Contamination:
    Platinum plated anodes do not dissolve into the electrolyte solution, maintaining its purity and preventing contamination. This is essential for processes that require high levels of cleanliness and precision.

  • Re-Plating:

    Using a dimensionally substrate material allows the anodes to be recoated numerous times to reduce overall lifetime cost.

Design Considerations for PLATINUM PLATED ANODES

  • Substrate Material:
    Titanium and niobium are commonly used substrates due to their high mechanical strength and compatibility with platinum plating.

  • Platinum Coating Thickness:
    The thickness of the platinum coating can be tailored to meet specific application requirements, balancing performance and cost.

  • Anode Shape and Size:
    Anodes can be manufactured in various shapes (e.g., mesh, rods, plates) and sizes to fit different equipment and process needs.

  • Electrical Connections:
    Reliable electrical connections are crucial to ensure consistent current flow and prevent potential points of failure.

platinum plated anodes maintenance and care

  • Regular Inspection:
    Periodic inspections are necessary to detect any signs of wear or damage to the platinum coating, which could affect performance.

  • Cleaning:
    Anodes should be cleaned periodically to remove any buildup of residues that could hinder their efficiency.

  • Replacement:
    Although platinum-plated anodes have a long lifespan, they will eventually need replacement. Monitoring their performance and replacing them as needed ensures continued optimal operation.
