Abstract

A process for the electrodeposition of a nickel chromium alloy on a catho substrate comprises: PA0 contacting the substrate with an aqueous electrolyte containing: about 50-125 g/l of CrCl.sub.3.6H.sub.2 O; about 10-125 g/l of NiCl.sub.2.6H.sub.2 O; about 10-115 g/l of formic acid; about 25-50 g/l of boric acid; and about 50-100 g/l of sodium citrate dihydrate; PA0 adjusting the pH of the bath to about 1-5 and the temperature to about 20.degree.-60.degree. C.; and PA0 passing a sufficient current through the solution and to the substrate to effect deposition thereon of a nickel-chromium alloy.
