摘　　要：采用MLD 10动载磨粒磨损试验机研究了等温处理和水淬对高碳Fe-0.9C-2.5Si-2.9Mn钢冲击磨损性能的影响。结果表明,在2 J低冲击功下,贝氏体、贝氏体/马氏体复相组织加工硬化层较浅,其磨损量高于马氏体组织,即马氏体耐磨性更佳;当冲击功增至6 J时,贝氏体组织表面形成了加工硬化层,其耐磨性得以提高,磨损量低于马氏体、贝氏体/马氏体复相组织。The influence of austempering temperature and water quenching on impact wear properties of high carbon Fe-0.9C-2.5Si-2.9Mn steel was studied using MLD 10 dynamic load abrasive wear tester. The results show that under 2 J low impact energy, the work hardening layer of bainite and bainite/martensite complex microstructure is shallower, and the wear quantity is higher than that of martensite microstructure, that is, the wear resistance of martensite is better. When the impact energy increases to 6 J, work hardening layer is formed on the surface of bainite structure, and its wear resistance is improved, and the wear quantity is lower than that of martensite and bainite/martensite multiphase structure.
