| Abstract: | The interface reaction and sintering mechanisms of a new Fe/SiC metal matrix composite (MMC) have been studied. The effects of the processing technological parameters on the properties of the material were analyzed. The results show that:the interface reaction can be effectively controlled when sintering at 1050℃. The principal mechanism of the interface reaction and the sintering of the composite is solid diffusion,and the interface binding and mechanical properties of the MMC can be improved remarkably by plating SiC particles with metal and matrix alloying, especially the wear resistance of the MMC. |
