Abstract：The regression formulas of structural ceramic materials erosive wear wereacquired by use of the multi-factors orthgonal experiment design.Combined with single-factorexperiments, this paper analyses the erosive wear character of three typical kinds of structuralceramic materials of SiC, Si,N,and AI.O3. The results of analyses are useful to application.
