试验发现，低应力冲击磨损（冲击能量为３．５Ｊ）以微切削为主，而高应力冲击磨损（冲击能量≈１６０Ｊ，与实况相近）以块状剥落为主，且其磨耗显著增大．材料组织类型影响高应力冲击磨损，贝／马复相组织具有优良的抗高应力冲击磨损性能．
It is found that the microcutting is the primary wear mechanism under low stress impact wear (3.5 J), while the delamination is of the primary one under high stress wear (about 160 J, which is similar to real one). The wear loss under high stress condition is also much more than low stress one. The wear mechanism of high stress wear is greatly affected by microstructures. The duplex of bainite and martensite has high wear resistance under high stress condition.
