A Study on Wear Resistance of the Ni-P-SiC Coating of Magnesium Alloy

Abstract:

Article Preview

The Ni-P-SiC composite coatings with homogeneous distribution were prepared through adding nano-SiC grains into the Ni-P chemical plating liquid. The morphology of the composite coatings was analyzed by SEM. The coatings microhardnesses at the SiC composite content for different concentration were measured using the microhardness tester. The wear property of coatings was evaluated by the friction-wear tester and the abrasion mechanism of coatings was also analyzed. The results show that the microstructures of the composite coatings are superior to the common coatings because the nano-SiC particles refine the crystal grains of the composite coatings. The hardness and wear resistance of the composite plating coatings were well improved under the strengthening effect of nano-SiC grains.The wear resistance was the best when the SiC concentration was 4g/L.
