Experimental Research and Performance Testing of Fe-Based Composite Plating

Abstract

By using self-made asymmetric AC - DC power supply and adding SiC in ferrous chloride bath, the high performance Fe-SiC iron-based composite coatings were 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 were studied. The process parameters of Fe-SiC composite plating were optimized. The results showed that the micro-cracks in composite coatings would reduced and the hardness, wear resistance and corrosion resistance will increased by adding SiC particles under the condition of optimum process.
