采用销盘式磨损试验机对3Cr3Mo2V铸钢和3Cr13钢在环境温度25℃和200℃下进行干滑动磨损试验,研究了显微组织和摩擦氧化物对3Cr3Mo2V铸钢和3Cr13钢磨损行为的影响,并探讨其磨损机制。结果表明:摩擦氧化物对25℃和200℃下的磨损行为和磨损机制有显著的影响,而摩擦氧化物的减磨作用取决于其数量和基体状态等,与钢的成分和显微组织密切相关。高的铬含量阻碍摩擦氧化物的形成,低硬度的回火索氏体加速氧化物剥落,故无摩擦氧化物的作用或作用降低。
The dry sliding wear test of 3Cr3Mo2V steel and 3Cr13 steel at ambient temperature of 25 ℃ and 200 ℃ was carried out with pin-plate wear tester. The effects of microstructure and friction oxide on the wear behavior of 3Cr3Mo2V steel and 3Cr13 steel were studied. And explore its wear mechanism. The results show that the frictional oxide has a significant effect on the wear behavior and wear mechanism at 25 ℃ and 200 ℃, while the frictional reduction of the frictional oxide depends on its quantity and matrix state, which is closely related to the composition and microstructure of the steel Related. High chromium content hinders the formation of friction oxides, low hardness of the tempered sorbite accelerated oxide spalling, so the role of frictionless oxide or reduced.
