摘　　要：采用熔渗法在炭/炭复合材料表面制备SiC/MoSi2双相涂层,研究涂层的微观结构和抗氧化性能。研究表明,采用熔渗法可以在炭/炭复合材料表面生成由SiC逐渐过渡到MoSi2的双相复合涂层,这种涂层在1300℃比1100℃拥有更优良的抗氧化性能,1300℃氧化15h试样质量增重2.9%,表明这种双相涂层具有良好的抗氧化保护性能。An anti-oxidation SiC/MoSi2 coating was prepared by Reactive Melt Infiltration in this paper.The microstructure and anti-oxidation performance was studied.The results show that the SiC/MoSi2 twin-phase coating could be made on carbon-carbon composites substrate,and this coating's performance of anti-oxidation is better at 1300℃ than that at 1100℃.The weight increased by 2.9% at 1300℃ after 15h oxidation.The results indicate that this coating has excellent anti-oxidation performance.
