采用多因素正交试验法，求出材料磨损的回归方法，并结合单因素试验，系统地研究了ＳｉＣ、Ｓｉ３Ｎ４和Ａｌ２Ｏ３三种典型结构陶瓷材料的冲蚀磨损特性．
The multi-factor orthogonal test method was used to get the regression equation of material wear. Combining with the single factor test, the erosion and wear characteristics of three typical ceramic materials of SiC, Si3N4 and Al2O3 were systematically studied.
