Method for preparing SiC coating based on carbon/carbon composite material surface and application thereof
The invention discloses a method for preparing a SiC coating based on the surface of a carbon/carbon composite material and application of the SiC coating. The SiC coating prepared on the surface of the carbon/carbon composite material matrix by adopting a double-layer glow plasma surface metallurgy technology can effectively protect the carbon/carbon composite material in an environment of 800 DEG C. The method has the advantages that (1) the ceramic-based coating is successfully prepared on the non-metal surface, and the frictional wear performance of a non-metal matrix at 800 DEG C is improved; and (2) C atoms of the substrate and Si atoms of the target material are subjected to atom bonding in a high-temperature sputtering environment by adopting a double-glow technology, so that the uniform and compact SiC coating with relatively high bonding strength with the substrate is obtained, and the phenomenon that the coating falls off in the service process is effectively avoided, so that the effects of protecting the workpiece and prolonging the service life of the workpiece are achieved. The prepared carbon/carbon composite material with the SiC coating can effectively protect the carbon/carbon composite material in a high-temperature service environment, and can be applied to the fields of automobiles, aviation and the like.
