Abstract

To improve the mechanical product hardness, wear resistance and corrosion resistance, Fe-SiC composite plating process and properties have been studied. By using self-made asymmetric AC - DC power supply and adding SiC in ferrous chloride bath, the high performance Fe-SiC composite coatings are prepared by electrodeposition method. The effect of Phase, composition and SiC particle content on the surface morphology, structure, hardness, wear resistance and corrosion resistance of Fe-SiC composite coatings are studied. The process parameters of Fe-SiC composite plating are optimized. The results show that the micro-cracks in composite coatings will reduced and the hardness, wear resistance and corrosion resistance will increased by adding SiC particles under the condition of optimum process.
