| Abstract: | The effects of adding the diluents Al2O3 and excessive Cr2O3 on the combustion synthesis reactive temperatures, and effects of heating rate on initial reactive temperatures in Al-Cr2O3 system were investigated. The compositions of the system were determined to get easily synthesized cermets melt and accomplish combustion synthesis. Cr-Al(Cr)2O3 cermets with fine Cr particles uniformly distributed in ceramic matrix have been successfully produced by combination of combustion synthesis and solidification technique of controlling the melt cooling condition. The cermets have relatively good oxidization resistance. |
