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.

为了开发耐磨表面层，研究了摩擦诱发表面层的摩擦冶金性能。对碳钢、纯铁和纯铜进行了销盘式滑动摩擦试验，并对滑动面附近的显微组织和硬度进行了详细的研究。结果表明，摩擦诱导层具有超细结构的销和盘表面上产生。在碳钢中发现了纳米晶结构和亚微米尺寸的晶粒。在高速滑动条件下产生的摩擦诱导层具有良好的耐磨性，表明摩擦加热引起的相变与超细组织的产生有关。
