At low cost, SiC_p/Al_2O_3-Al composites were synthesized by directed oxidation of metals(DIMOX).The
technical process is introduced in details. The microstructures of the composites were investigated using X-ray
diffraction(XRD) and scanning electron microcopy(SEM). The effects of SiO_2 layer clinging to SiC_p, the alloy
components and technical parameters on the properties were analyzed.The result indicates that the spontaneous
penetration is nearly perfect and the SiC_...
