Abstract: |
Since hexavalent chromium has bad effects on environment, research on the trivalent chromium electrodeposition has been accelerated. Thick chromium coatings are difficultly deposited from trivalent chromium bath, and chromium binaryalloy coatings have distinct advantages at deposit thickness. Electrodeposition technologies of Cr-Ni, Cr-Fe, Cr-Co, Cr-P, Cr-C and Zn-Cr from trivalent chromium bath were summerized. The binaryalloy coatings characteristics and application were briefly introduced also. Chromium binary alloy electrodeposited from trivalent bath promisingly will have a wide application prospect in industry. |
