Abstract
Conditions for the electrodeposition of Ni−Cu−Mo alloys from citrate electrolytes have been developed. The composition variations of the deposits with electrolyte pH and concentration have been investigated. A maximum molybdenum and nickel content is obtained for a pH of 7 and for low copper and large citrate concentrations. Molybdenum and copper are preferentially discharged at low current density whereas at high current density nickel becomes predominant. The deposits have a nodular morphology similar to that of the binary Ni−Mo layers
