通过对高锰钢的磨损表面形貌、磨屑形貌和表面硬度的分析，研究了氧化铝粒子的冲蚀速度对高锰钢的磨损特性的影响．结果表明：在氧化铝粒子不同速度的冲蚀下，高锰钢仍具有典型延性材料的冲蚀磨损特性．高锰钢的磨损过程分为两个阶段：初始阶段和稳定阶段．同一速度下初始阶段的磨损率高于稳定阶段的磨损率．随氧化铝粒子冲蚀速度的提高，在高锰钢的冲蚀磨损过程中出现稳定阶段所对应的粒子质量逐渐减少，初始阶段和稳定阶段的磨损率都增加，表面硬化层的厚度和应变诱发马氏体的分数有所增加．
By analyzing the wear surface morphology, wear debris morphology and surface hardness of high manganese steel, the impact of erosion rate of alumina particles on the wear characteristics of high manganese steel was studied. The results show that the high manganese steel still possesses the erosion wear characteristics of typical ductile materials under the erosion of alumina particles at different speeds. High manganese steel wear process is divided into two stages: the initial stage and the stable stage. The wear rate of the initial stage at the same speed is higher than that of the steady stage. With the increase of the erosion rate of alumina particles, the particle quality corresponding to the stable phase in the erosive wear of high manganese steel gradually decreases, the wear rate in the initial phase and the steady phase increases, the thickness of the hardened layer and the strain induced The fraction of martensite has increased.
