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.
