Paper Title:
Industrial Preparation of SiC Ceramic Coating for High Temperature and Anti-Oxidation of C/C Composites
  Abstract

A SiC ceramic coating for high temperature and anti-oxidation was prepared by high temperature reaction and PVD methods inside industrial synthetic furnace of SiC. Its phase composition and microstructure were characterized by using XRD, SEM,and its high temperature anti-oxidation property were studied by isothermal oxidation tests.The results showed that the coating is composed of mainly α-SiC and β-SiC,the coating is uniform, compact, perfect grain growth, without crack, closely with the C/C materials,the thickness is about 600μm. After 10h oxidation in air at 1773 k the weight loss of the coating was only 0.3%,which implies that the coating has excellent anti-oxidation ability.
