The processes of electrodeposition of coatings with zinc-nickel alloys (3–16 at.% Ni) for steel 17G1C-U from oxalate-ammonium electrolytes were investigated. The influence of the alloy component ratio on the corrosion resistance of the coatings, kinetic parameters of electrodeposition, and the structure was demonstrated. It was found that zinc-nickel coatings reduce their corrosion current up to 7 times compared to that of zinc coatings. The microhardness of high-alloyed nickel coatings increases by 1.8 times compared to that of low-alloyed zinc-nickel coatings.
Keywords: electrolytic deposition, zinc-nickel alloy, corrosion resistance, surface roughness.
