This invention belongs to the field of ceramic composite material manufacturing technology, specifically relating to a method for preparing SiC composite materials based on cold spraying and silicon infiltration. SiC powder is prepared into a suspension, which is then deposited onto a substrate using a cold gas-powered spraying system to form a porous SiC preform coating. The preform coating undergoes post-curing to enhance its cohesive strength. Finally, melt silicon infiltration is performed, causing silicon to react with carbon in the preform to generate a new SiC phase that fills the pores, resulting in a high-density, high-performance SiC composite component. This method combines the advantages of low-temperature forming in cold spraying with silicon infiltration technology. The relatively low substrate temperature during cold spraying effectively avoids the adverse effects of high temperatures on the material structure, maintaining the stability of the original SiC phase. By adjusting the spraying parameters and matching the silicon infiltration process, the free silicon content and the distribution of the newly generated SiC phase in the composite material can be precisely controlled, further improving the material's density and mechanical properties.
