| 摘 要： | 研究了不同热处理工艺和磨损冲击功对变质Ｍｎ８钢耐磨性的影响。结果表明，在相同的热处理工艺条件下，变质Ｍｎ８钢的耐磨性随磨损冲击功的增大呈先增后减的规律，在１Ｊ磨损冲击功处出现耐磨性峰值；在１Ｊ磨损冲击功条件下，变质Ｍｎ８钢的耐磨性以弥散处理时最好，固溶处理时次之，时效处理时最差，且耐磨性随时效温度的提高而降低；在０．５Ｊ、１Ｊ和２Ｊ磨损冲击功时，变质Ｍｎ８钢的主要磨损机制分别为显微切削＋凿坑变形、显微切削＋浅小凿坑＋轻微剥落、累积变形疲劳剥落；最佳耐磨性时的磨损机制为显微切削＋浅小凿坑＋轻微剥落

| Abstract: | Effect of heat treatment and wear impact energy on wear resistance of modified Mn8 steel has been investigated in this paper The experimental results show that the wear resistance of modified Mn8 steel heat treated by certain condition increases first, then decreases with the increment of impact energy, and the maximum value is resulted from impact energy At impact energy of 1 J, the wear resistance of the steel treated for dispersion is the highest, that of the steel treated for solid solution is the second and that of aging treated is the lowest Meanwhile, the wear resistance drops with the raise of aging temperature At the impact energy of 0 5 J, 1 J and 2 J, the principal wear mechanism of the steel is microcutting gouging deformation, microcutting small gouging hole light spalling and accummulating deformation fatigue, respectively The wear mechanism corresponding to the maximum resistance is the microcutting small gouging hole light spalling |
