Abstract: In a solution for electroplating Cr in which the source of Cr ions is an aqueous equilibrated solution of Cr (III) thiocyanate complex, the improvement comprises a buffer in the solution which provides one of the ligands for the complex. The buffer is an amino acid, peptide, formate, acetate or hypophosphite. Specifically the amino acid is glycine, aspartic acid, arginine or histidine. The deposition of Cr is facilitated at high current densities, both by catalytic effect of the thiocyanate and by the intimate buffering at the cathode by the amino acid released from the Cr atom as it discharges onto the cathode.
