英文摘要	A composite material containing silver and molybdenum metals was fabricated by powder metallurgy method with a Ag/Mo molar ratio of 2:1 and the sintering temperature is 700 degrees C. Tribological properties, especially the solid lubrication behaviours during oxidation of the composite in air, were considered from room temperature to 600 degrees C. Phase composition, microstructure and thermal behaviour of the composite were analysed before and after tests to investigate the lubrication mechanisms. The friction coefficients of the composite are similar to 0.7 below 400 degrees C but decrease sharply to similar to 0.18 above 500 degrees C. Characterisations of this composite indicate that several silver molybdates (Ag2MoO4, Ag2Mo2O7 and Ag2Mo4O13) formed from oxidation of Ag-Mo composite at high temperatures benefit lubrication effects and lead to the decrease of friction coefficients. Formation mechanism of these silver molybdates during oxidation and wear was therefore studied, and a model based on solid reaction processes in the Ag-Mo-O-2 system was promoted.
