对比研究了碳化铬/Ni3Al复合材料和传统高温耐磨材料Stellite 6合金和T800合金的室温耐微动磨损性能。结果表明,碳化铬/Ni3Al复合材料具有优异的耐微动磨损性能,与GCr15对磨时,其室温相对耐磨性分别是Stellite 6和T800合金的5.5倍和2.6倍。通过分析微动磨损机制认为,碳化铬/Ni3Al复合材料优良的耐微动磨损性能可以归因于材料优良的耐磨粒磨损性能、均匀的碳化铬颗粒分布、合理的碳化物增强相尺寸搭配和Ni3Al合金基体优良的力学性能。
The room-temperature fretting wear behavior of chromium carbide/Ni3Al composite and conventional high temperature wear-resistant materials such as Stellite 6 alloy and T800 alloy was investigated comparatively.Compared with Stellite 6 alloy and T800 alloy,chromium carbide/Ni3Al composite possessed higher fretting wear resistance.The fretting wear resistance of chromium carbide/Ni3Al composite was respectively 5.5 times and 2.6 times of that of Stellite 6 alloy and T800 alloy.The good wear resistance of chromium carbide/Ni3Al composite can be attributed to good abrasive wear resistance,the reasonable size distribution of reinforcements,and good mechanical properties of Ni3Al matrix.
