摘要

根据 Al-TiC、Al-Bi（RC）和 Al-Bi-TiC 合金的摩擦和磨损对比实验，系统地研究了 TiC/Bi 的减摩和耐磨机理。通过配备了能量色散光谱仪和形状测量激光显微镜（VK-X100）的扫描电子显微镜对合金进行了检测。研究结果表明，双相在摩擦表面逐渐富集，在摩擦表面具有减摩和自润滑作用。稳定的 TiC/Bi 自润滑层使 Al-Bi-TiC 合金的磨损测量值在 2 h 内从 82.2 mg 降至 26.7 mg，同时 TiC 颗粒具有均匀的承载能力和界面针刺特性，解决了 Bi-phase 从磨损表面剥离的问题。

Effect of TiC/Bi on Self-Lubricating Properties of Al–Bi-TiC Alloy

According to the comparative experiments on friction and wear of Al–TiC, Al–Bi (RC) and Al–Bi–TiC alloys, the friction-reduction and wear-resistance mechanisms of TiC/Bi were systematically investigated. The alloys were examined via the scanning electron microscope equipped with an energy dispersive spectrometer and a shape-measuring laser microscope (VK-X100). Basing the achievements, the Bi-phase accumulates on the friction surface with gradual enrichment, possessing anti-friction and self-lubrication on the friction surface. The stable TiC/Bi self-lubricating layer of Al–Bi–TiC alloy make the values of the wear measurements reduce from 82.2 mg to 26.7 mg in 2 h. Meanwhile, TiC particles have uniform load capacity and interfacial pinning properties, which solve the peeling off from the worn surface of Bi-phase.
