Abstract
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.
期刊介绍：
Tribology Letters is devoted to the development of the science of tribology and its applications, particularly focusing on publishing high-quality papers at the forefront of tribological science and that address the fundamentals of friction, lubrication, wear, or adhesion. The journal facilitates communication and exchange of seminal ideas among thousands of practitioners who are engaged worldwide in the pursuit of tribology-based science and technology.
