摘　　要：本文分析讨论了近年来材料冲蚀研究进展，总结出只有当入射角度非常低或入射粒子粒径相当小时，脆性材料的冲蚀率才有可能比韧性材料的冲蚀率低；决定韧性材料抗冲蚀性能的关键因数并不是材料的硬度而是材料的弹性模量；The developm ent of research in erosion of m aterials is sum m arized and discussed in this pa per. It is concluded that only w hen the grazing angle is vary low or the abrasive particles size is very sm allare brittle m aterials m ore resistantto erosion than ductile m aterials. The key factor w hich affects erosion re sistance is elastic m odulus rather than hardness ofm aterials. The behavior of therm al sprayed coatings is asthat of brittle m aterials.
