摘　　要：以45钢、钛铁、生铁等为主要原料,在大气环境下、利用中频感应电炉、通过添加含氮附加物、采用原位反应铸造法制备了Ti(C,N)颗粒增强铁基复合材料。研究了所制备复合材料的油润滑摩擦磨损性能、干摩擦磨损性能以及冲击磨料磨损性能。结果表明,在有润滑和无润滑条件下的干摩擦,复合材料的耐磨性能都远大于正火45钢;在中、低冲击工况下,复合材料磨料磨损性能优于高锰钢和高铬铸铁。Taking 45 steel, titanium iron, pig iron as main raw material, in the atmospheric environment, Ti （C,N） particles reinforced Fe-based composite was prepared by in-situ reaction casting. And the friction and wear properties in the conditions ofoil lubrication and dry friction, and the impact abrasive wear resistance of the composite were studied. The results show that the friction and wear properties of the composites are much larger than normalizing 45 steel under lubricated and non- lubricated conditions; the abrasive wear resistance of the composite is better than the high manganese steel and high chromium cast iron in the middle and low-impact conditions.
