| 摘 要： | 在TC11钛合金表面等离子渗Mo以提高其耐磨性。利用SEM、EDS、XRD分析了渗Mo层的微观组织、化学成分及相组成,测定了渗层的硬度分布。采用划痕试验测定了渗层与基体的结合力。通过球盘磨损试验测定了等离子渗Mo层的摩擦磨损性能。结果表明,渗层厚度为30μm;0～10μm表层Mo含量为65%,由表及里呈梯度降低;渗层由单质Mo以及Al8Mo3和Al3Ti等化合物组成,表面硬度达1034 HV0.1;渗层与基体的结合力为70 N;渗层的比磨损率是基体的1/55.4。

| Abstract: | TC11 titanium alloy was plasma molybdenized to improve on its wear resistance.The microstructure,chemical composition and phase structure of the molybdenized case were analyzed by means of SEM,EDS and XRD.The hardness profile of the molybdenized case was measured.The adhesive strength of molybdenized case with substrate was evaluated by scratch test.The tribological behaviors of molybdenized case were investigated by ball-on-disc rubbing test.The results are that:(a) the molybdenized case is as thick as 30 ... |
