Surface modification and performance depend largely on the properties of surface atoms and structures. Fundamental investigation of friction was conducted in a Cu-Al sliding system. Deformation, wear, and transfer were studied. Detailed study was focused on friction-induced phase transformations. Surface characterization was carried out using an atomic force microscope (AFM). The debris analysis was done using a transmission electron microscope (TEM). Results showed that debris formed during sliding were amorphous. On the wear track, there is indication of surface melting and hardening. This presentation will discuss wear mechanisms involved in oxidation and property-performance of metallic materials.
