摘要：
A mullite/yttrium silicate bilayer coating was prepared by plasma spray method as an oxidation protective coating. The morphology, composition, microstructure and adherence strength of the coating were analyzed. The efficiency of the coating against oxidation was characterized by heat treatment of the C/SiC composites at 1500 degrees C in static air for 1 h. The structural change of the coating was studied, and the mass and flexural strength of the C/SiC composites before and after the heat treatment were investigated. The results indicate that the mullite/yttrium silicate bilayer coating exhibits excellent oxidation resistance as the flexural strength of the composites retains 95.3% of the original strength.
