%X Cr-(Al,Cr)2O3 cermets with relative density of about 90% have been successfully produced by thermo-explosive combustion synthesis and under pressure on the melt. Cr particles with minimum size of about 200 nm are distributed in ceramic plates or boundary between ceramic plates. The cermets have good wear resistance property under dry sliding. The wear volume of samples is related to addition amount of diluents Al2O3 and excessive Cr2O3.Through rational balance of them, the wear volume of Cr-(Al,Cr)2O3 is lower than that of powder sintered alumina ceramic. The main wear mechanism of the cermets is the peeling off under dry sliding. In oil lubrication, there is little wear volume loss in the sample under loading of 147 N and 6000 m sliding distance. The wear volume of the cermet is increased with loading, but is smaller an order of magnitude than that of Cr12MoV steel.
