Research Abstract

Porous Fe-Mo alloy coating specimens were prepared by low pressure plasma spraying, and their friction and wear properties were investigated in PAO containing no additives. It was found that the main phase of the coating can be changed by changing the arc current. In addition, we prepared some kinds of alloy disk specimens using spark plasma sintering, and their tribological properties were also examined. It was found that Fe-Si alloys are low friction and low wear rate materials.
