摘要 | Ni-Co-Al high temperature alloys with different Co content were prepared by powder metallurgy (mechanical alloying and hot-press sintering), of which the high temperature tribological properties were investigated at 800. The results showed that the hardness and compressive strength, as well as the tribological properties of alloys could be improved with a Co addition in a range from 5-30 mass%, among which 20 mass% is the optimal. The observation of worn surfaces by SEM, XPS and EDS revealed that a "glaze-like film" consisted of CoO and other oxides existed on the worn surface. The high temperature tribological properties of the alloys are highly related with the composition and the spallation tendency of the formed glaze film during the friction and wear process. © Copyright. |
