| Abstract: | The wear characteristics of the PM Al 10Ti alloy during dry sliding have been investigated. The wear process can be divided into the running in stage with high wear rate and the steady state stage exhibiting mild wear. The transfer layers develop due to deformation, compaction, fracture and adhesion. The oxides consisting of Al 2O 3 and Fe 2O 3 are formed on the worn surface and they reduce wear. Transition from running in to steady state wear is caused by strain hardening of subsurface and oxidation of the surface. At the steady state wear stage, detachment of wear particles is mainly ascribed to delamination of transfer layers. |
