Abstract:The temperature dependences of the coefficients of friction and the wear rates of several Fe-Re alloys containing various Re contents were determined with a pin-on-disc high-temperature wear device. The examination, analysis and determination of the debris, the wear scars and the load-bearing oxide films were performedusing SEM,X-ray diffractometer, electron probe and microhardness tester. The results showed that after hightemperature sliding, there were formed surface glaze layers in the studied Fe-Re alloys, and the sub-surface layers were composed of ductile oxides and deformed matrix alloys. The presence of large amounts of iron oxides on the load-bearing oxide layers resulted in the high hardness platforms and the good high-temperature wear resistance of the alloys. The oxides of Re and Fe(ReO4)3 present in the skeletons of iron oxides play the role of lubricating at high temperatures.
