| Research Abstract |
Tribo-metallurgical properties of friction-induced surface layers were studied in order to develop anti-wear surface layers. 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 friction-induced layers with ultra-fine structures were produced on the pin and disc surfaces. Nanocrystalline structure and submicron size grains were identified for carbon steel. The friction-induced layers which were produced at a high sliding speed on a steel pin showed good wear resistance, suggesting that phase transformation by friction heating is associated with the ultra-fine structure production.
