Research on Preparation and Properties of Antiwear and Anticorrosion Composite Coating Ni-P-SiC

Abstract:

Ni-P-SiC composite coatings on the surface of ZL102 aluminum alloy were prepared by direct electroless plating. The structure and morphology of the coatings after heat treatment at 400 °C for 1 hour were analyzed by XRD and SEM. The bonding strength, hardness, corrosion resistance and wear resistance of the coatings were tested. The results show that the coatings structure is crystalline and the main crystal phase is Ni₃P. The SiC particles are evenly distributed in the coatings. The coatings have uniform thickness, high bonding strength and high micro hardness (up to 1395.28 HV.2). It is also shown that the substrate corrosion resistance and wear resistance can be considerably improved after electroless plating.
