Abstract

A flow plating system was used to investigate chromium metal deposition from an electrolyte based on Cr(iii) and glycine. The Cr(iii) glycine species suitable for chromium deposition was identified. The chemical reactions occurring during electrolyte preparation and during metal deposition are discussed. Chemical reaction sequences for the predominant reactions are suggested. The influences of the chromium ion concentration, temperature and electrolyte velocity on chromium deposition are considered. The optimum conditions for good quality chromium metal deposition are determined.
