A Study on the Ni-P-SiC Coating of AZ91D Magnesium Alloy
An Investigation on the Ni-P-SiCp Electroless Composite Plating of AZ91D magnesium alloy was investigated.The morphology and phase structrue of the electroless composite plating were investigated by means of SEM and XRD.The effect of concentration of the second phase particle in electroless plating solution on wear resistance of the Ni-P-SiCp composite coating were studied.The properties of the coatings before and after heat treatment were compared.The result shows that the obtained coatings were flat and compact.X-ray diffractometry indicated that the coatings were amorphous,but crystallization would happen in the process of heat treatment.From the lost weight of the coatings it can be seen that the wear resistance of composite coatings was better than that of Ni-P coatings .
