本文通过加适量Ｍｎ，在铸态下获得了奥氏体基体高铬铸铁，并通过冲击试验和３种磨损试验比较并讨论了奥氏体高铬铸铁与马氏体高铬铸铁的磨损特性以及在不同磨损条件下的磨损机制。试验结果表明：在有冲击作用的磨损场合下，奥氏体高铬铸铁可表现出较好的韧性与耐磨性能匹配，其耐磨性高于马氏体高铬铸铁，且冲击功越大，磨损失重越少，耐磨性越高。 In this paper, the austenitic matrix high chromium cast iron was obtained by casting an appropriate amount of Mn. The wear characteristics of austenitic high chromium cast iron and martensite high chromium cast iron were compared and discussed by the impact test and three kinds of wear tests. Wear mechanism under different wear conditions. The test results show that the austenitic high chromium cast iron can exhibit good toughness and wear resistance matching under the impact wear condition and the wear resistance is higher than that of the martensite high chromium cast iron and the impact energy is larger, The less abrasion loss, the higher wear resistance.
