| 摘 要： | 通过微弧氧化技术(Micro-arc oxidation, MAO)对TC4合金进行表面处理,探究了不同MAO电压对TC4合金氧化膜层摩擦磨损性能的影响。使用激光共聚焦显微镜、扫描电镜、X射线衍射仪、显微硬度计及高温真空摩擦磨损试验仪对膜层形貌、相成分、硬度以及摩擦学性能进行了测试。结果表明:随着MAO工作电压的升高,MAO-TC4合金表面膜层中锐钛矿型TiO2和金红石型TiO2的含量随之增加,其表面粗糙度、显微硬度以及平均摩擦因数亦随之增大,磨损率先降低后增大。当MAO工作电压为280 V时,磨损率最小,为2.8 mg/cm2,摩擦磨损性能最佳。

| Abstract: | Effect of micro-arc oxidation(MAO) voltage on friction and wear properties of the TC4 alloy oxide film prepared via MAO technology was studied. The morphology, phase composition, hardness and friction and wear properties of the oxide film were tested by means of laser confocal microscope, scanning electron microscope, X-ray diffractometer, micro-hardness tester and high temperature vacuum friction and wear tester. The results show that with the MAO voltage increasing, the content of Anatase-TiO2 and Rutile-TiO2 in the MAO-TC4 alloy surface oxide film increases, and the surface roughness, microhardness and average friction coefficient of the oxide film also increase, while the wear rate of which first decreases and then increases. When the MAO voltage is 280 V, the optimum friction and wear property of the MAO-TC4 alloy oxide film is obtained, with the minimum wear rate of 2.8 mg/cm2. |
