Electrodeposition of Fe-Cr-Ni ternary alloys from mixed solutions of metal chlorides and glycine at pH 2.4 was investigated with emphasis on the state of the Cr (III) complex ions. The Cr (III) complex changed its form from a hexa-aquochromium (III) complex to an unidentified complex coordinated with glycine molecules when the solution was cathodically electrolyzed for a certain time. Electrodeposition from the solution containing the aged complex showed relatively good throwing power, and the solution was stable.
