Platinized titanium anodes are an excellent alternative for hard chrome plating since they offer many benefits in hard chrome plating. Processes with platinum coated titanium anodes are almost completely free of lead and therefore considerably more environmentally friendly.
There is no lead chromate, fewer health risks for workers, and no disposal costs. Production downtime and exchanges are not required, as with lead systems.
Trivalent chromium electrolytes have advantages over those of hexavalent chromium in terms of health and safety and toxicity to the environment. However, selection of appropriate anodes is significant. Since trivalent chromium plating solution is sensitive to impurities and unstable, insoluble anodes used should be used in the plating bath.
Insoluble anode does not dissolve or is substantially insoluble in the matrix of the plating bath, it includes lead, lead alloy, platinized titanium anodes, titanium anode or metal anodes comprising a surface coating comprising iridium oxide, ruthenium oxide or mixed iridium tantalum oxide.
The product shown in the photograph is used for the application “Trivalent Chrome Plating” made up of titanium and coated with MMO.
