The Effect of Temperature on the NiCu Coating Prepared 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 temperature on the as-plated NiCu coatings are systematically researched. It was found that the lower of the temperature, the more compact of the coatings. With the increasing of the temperatures, the content of the nickel decrease and that of the copper increase. When the temperature is lower than 35 °C the contents of nickel and copper do not vary apparently. When the temperature is larger than 40 °C, there are significant increases of the copper content while apparent decreases of the nickel content.
