摘要：

Sliding friction tests of pin-on-disc type were carried out for carbon steel, pure iron and pure copper, and the microstructure and hardness near the sliding surfaces were investigated in detail. It was found that patchy transfer layers with ultra-fine ( < 200 nm) structures were produced on the disc surfaces. Nanocrystalline grains of 30-50 nm were identified for carbon steel, and submicron sized grains of 100-150 nm were observed in pure copper. The thicknesses of the ultra-fine structures were in the range of 10-50 mu m, depending on the specimen material, sliding speed and applied load. The hardness near the sliding surface of pure iron was increased compared with the matrix. It was suggested that the hardening was due to the very fine structure formed by severe plastic deformation, but not due to phase transformation caused by thermal effects. (C) 2009 Elsevier Ltd.
