Preparation of SiC-Low Chromium Cast Iron Composite Material by Cast-Infiltration

Abstract:

Article Preview

Low-chromium cast iron as the matrix, SiC particles as reinforcement, water glass sand in ordinary dry type, no negative pressure conditions, the use made of composite diffusion agent, prepared the surface of SiC particulate reinforced steel matrix composites. The results show that: SiC particles penetrate the surface of the composite material has excellent wear resistance, with the content of SiC particles increase the wear resistance of composite cast layer increased, when the SiC particle content of 20%, the wear resistance to achieve the best good. The hardness of up to 3000HV composite layer above. Smooth casting surface roughness, dimensional accuracy is more accurate, composite layer and substrate is good.
