摘 要: 以新型含TiC马氏体钢Ti60和商用不含碳化物马氏体钢JFE400为研究对象，通过三体磨料磨损试验机研究
在纯煤粉和纯煤粉掺杂40%(质量分数)石英砂为磨料下，TiC硬质相对低合金马氏体钢磨料磨损性能的影响及其作
用机理. 结果表明：在纯煤粉环境下，Ti60钢的磨损体积大于JFE400钢；但在纯煤粉掺杂40%(质量分数)石英砂环境
下，Ti60钢的磨损体积却小于JFE400钢. 根据磨痕表面的形貌，上述结果是由以下几方面综合作用造成的. 首先，两
种环境下材料的磨损机制均主要是犁削磨损；其次，煤粉颗粒的层状结构及低硬度的特性，使得TiC硬质相对其犁
削行为起不到阻碍作用，而块状结构且具有高硬度的石英砂颗粒的犁削行为则受到TiC硬质相的阻碍. 所以在纯煤
环境下，基体硬度较大的JFE400钢，相对于基体硬度较小的Ti60钢，呈现出较优的抗磨料磨损的性能. 而在纯煤粉
掺杂40%(质量分数)石英砂环境下，Ti60钢的抗磨粒磨损性能却优于JFE400钢.

Abstract: A new type of TiC- containing martensitic steel Ti60 and another type of commercial martensitic steel JFE400
without carbide were used as the research objects. The effect of TiC hard phase on the abrasive wear performance and its
mechanism of a low alloy martensitic steel were studied using three-body abrasive wear tester under the condition of
pure coal powder and 40% quartz sand doped with pure coal powder as the abrasive. The results showed that the wear
volume of Ti60 steel was greater than that of JFE400 steel in the pure coal powder environment. However, the wear
volume of Ti60 steel was lower than JFE400 steel under the condition of coal powder doped with 40% quartz sand.
According to the surface morphology of the worn marks, the above results were caused by the combined action of the
following aspects. Firstly, the wear mechanism of materials in both environments mainly was microploughing wear.
Secondly, due to the layered structure and low hardness of coal powder particles, TiC hard phase did not play an obstacle
role with its ploughing behavior, while the ploughing behavior of massive structure quartz sand particles with high
