Cf/SiC composite are widely used in aerospace, chemical industry, traffic, and many other fields because of good mechanical properties, heat resistance, thermal shock resistance and abrasion resistance, corrosion resistance, etc. But its oxidation resistance is poor in the application of high temperature environment. In this paper, high-temperature ceramic coating was prepared on Cf/SiC composites surface through brush painting method and the oxidation resistance of the coating were studied. The coating was tested by XRD, SEM, etc. The results showed that the coating and composite matrix is good combination, at the same time the coating has good oxidation resistance.

MoSi2 is a potential matrix material for high temperature structural composites due to its high melting temperature and good oxidation resistance at elevated temperatures. The two major drawbacksfor structural applications are inadequate high temperature strength and poor low temperature ductility. The search for appropriate composite additions has been the focus of extensive investigations in recent years. The addition of SiC in a nanolayered configuration was shown to exhibit superior oxidation resistance and significant hardness increase through annealing at 500°C. One potential application of MoSi2- SiC multilayers is for high temperature coatings, where structural stability ofthe layering is of major concern. In this study, we have systematically investigated both the evolution of phases and the stability of layers by varying the heat treating conditions.Alternating layers of MoSi2 and SiC were synthesized by DC-magnetron and rf-diode sputtering respectively. Cross-sectional transmission electron microscopy (XTEM) was used to examine three distinct reactions in the specimens when exposed to different annealing conditions: crystallization and phase transformation of MoSi2, crystallization of SiC, and spheroidization of the layer structures.
