Abstract (en)
[origin: WO8203095A1] High-speed plating of corrosion-resistant, chromium alloy coatings from divalent/trivalent chromium solutions is feasible with high current densities, rapid solution flow and careful control of pH. Chromium-iron-nickel alloy coatings are plated on copper cathodes, for example, from trivalent chromium baths at 30 microns per minute and 160 A/dm<s2>s. Current densities in the range of about 75-400 A/dm<s2>s (5-26 A/in<s2>s) are most useful.
