Abstract
Electrodeposition from trivalent chromium baths as an environmentally friendly alternative to electroplating from hazardous hexavalent chromium baths
Author(s): V.S.ProtsenkoThe paper dealswith the generalization of investigations concerning current state in development of trivalent chromiumbaths as environmentally friendly alternative to hazardous electroplating baths containing toxichexavalent chromium.Themain technological properties of trivalent chromiumbaths containing carbamide and formic acid are described and comparedwith those typical of common Cr(VI) plating bath.Thick nanocrystalline chromium-carbon deposits may be obtained from the Cr(III) electrolytes, some physicochemical and service properties of such coatings exceeding those of “usual” chromiumdeposits.
