| Sumario: | Ni-Cr alloy sliding tests in the atmosphere at 1000 °C which is higher than the temperatures used in the conventional research were carried out and observed the process in which glazed oxide layer is formed on the wear track. By the analysis of the element distribution on the cross-section of the glazed oxide layer formed on the wear track after the friction had been reduced, we have clarified that the glazed oxide layer formation process is the same as the process found by the conventional research. Furthermore, the discharge of wear particle necessary for the formation of glazed oxide is further promoted at 1000 °C and therefore glazed oxide begins to form on the comparatively early stage, thereby showing low friction and low wear. |
