Preparation of Electrodeposited Cr-Nd Coating and its Properties

Abstract:

Cr-Nd coating was prepared by electrodeposition method. The microhardness, wear weight loss and friction coefficient of Cr-Nd coating were studied respectively. The Cr-Nd coating were characterized with ICP-AES, EDAX, XRD and SEM techniques, respectively. The micro-hardness and the wear weight loss, friction coefficient of the Cr-Nd coatings are higher and lower respectively than that of the Cr coating. The microhardness of the Cr-Nd is as high as 815.6 HV, which is higher 4.16% than that of the Cr coating (783.0 HV). The wear weight loss of Cr-Nd is lower 1.33 times than that of Cr coating. The friction coefficient of Cr coating and Cr-Nd coating are 0.896 and 0.714 respectively. There are crystalline CrC in Cr-Nd coating. There are nodules on Cr coating surface. There are not nodules on Cr-Nd coating surface. Cr-Nd coating surface is smooth.
