The Influence of pH Value on the NiCu Coating Synthesized by Electroplating

Article Preview

Abstract:

In this paper, the NiCu alloy coatings were electroplated on the 304 stainless steel coupon. The XRD was used to identify the phase structure of the as-prepared products. The SEM and EDS were used to observe the surface morphology of the as-prepared coatings and the atomic composition of the as-prepared coatings, respectively. The influences of the pH value on the as-plated NiCu coatings are systematically researched. It was found that the weak acid environment was beneficial to the deposition of nickel copper alloy. With the increasing of the pH value, the content of the copper decrease and that of nickel increase.
