Preparation and Performance of Electrodeposited Cr-Pr Coating

Abstract:

Cr-Pr coating was prepared by electrodeposition method. The microhardness, wear weight loss and friction coefficient of Cr-Pr coating were studied respectively. The Cr-Pr coating were characterized with ICP-AES, EDAX, XRD and SEM techniques, respectively. The microhardness and the wear weight loss, friction coefficient of the Cr-Pr coatings are higher and lower respectively than that of the Cr coating. The microhardness of the Cr-Pr is as high as 805.2 HV, which is higher 3.74% than that of the Cr coating (776.2 HV). The wear weight loss of Cr-Pr is lower 1.33 times than that of Cr coating. The friction coefficient of Cr coating and Cr-Pr coating are 0.884 and 0.723 respectively. There are crystalline CrC in Cr-Pr coating. The nodules on Cr-Pr coating surface are smaller than that of Cr coating surface, and furrows and spalling are lower on the worn surface of Cr-Pr coating than that of the Cr coating.
