英文摘要A laminar-structured tribolayer on the worn surface of Cu–SiO2 composite in sliding against 1045 steel is observed by etching the longitudinal sections. In morphology, the tribolayer consists of many subunits with different lengths and heights. The subunits are curved or parallel to the contact surface at different depths from bulk to the worn surface. In microstructure, the tribolayer is unconsolidated after etching, and fine Cu grains, as well as few fractured SiO2 particles, are observed. The main formation mechanism of the laminar-structured tribolayer is grain boundary sliding. Shear localization with large plastic strain is a prerequisite for the formation of laminar structure. The generation and accumulation of frictional heating promote the plastic deformation and decrease the activation energy for grain boundary sliding. The etching effect is contributed to the presentation of the laminar structure.
