Study on Erosion Wear Property of Self-Bonding Silicon Carbide Wu Qide; Zhu Qi; Li Ningfang; Wu Xiaobing; Liu Qingguo(Lect.,Saimai Company, WUT,Wuhan 430070,China.)The erosion wear property of self-bonding SiC (RSSC) has been studied by erosion reducing grarity and microstruclune analyse methods. The experiment results experess that the wear resistance of RSSC is better then other engineering ceramicses when it is eroded at low angle,its wear resistance at hiht angle concerns with grain phase. In this paper the principle of designing wear material used low angle erosion has been proposed and from this the result of industry explement is good.: SiC; reaction sintering microstructure; erosion wear
