Composite electrochemical coatings with a carbon-containing dispersed phase or polytetrafluoroethylene

Composite electrochemical coatings based on nickel, zinc, and chromium were studied. The dispersed phase of these coatings is constituted by graphite, diamond, and polytetrafluoroethylene produced from wastes formed in manufacture of fluoroplastic and ultradispersed diamond produced from industrial waste. The conditions in which high-quality coatings with best characteristics, such as microhardness and corrosion resistance, were determined. The wear resistance was additionally found for the chromium-diamond coating.
