ABSTRACT:
An electroplating bath and process for producing a nickel-zinc alloy electrodeposit containing about 8% to 35% nickel characterized in that the bath is essentially a boric acid-containing sulfamate bath maintained at a pH of 2.5 to 4.0 and operated at a cathode current density of about 10 to 25 mA cm.sup.-2 and at a temperature of about 20.degree. C. to 70.degree. C.
