This paper use casting to make the composite material of particle
of SiC and the base of steel .The distributing of SiC in the composite
material and the decomposer of SiC and interface between steel and
SiC are analyzed too. At the same time, The contrast of mechanical
features,for example hardness,wearness and so on,between basic
material and composite material are also tested .The paper emphasize
mechanism of the composite material, applyi...
