| Abstract The aim of this research is to study microstructure and some mechanical properties of ceramic matrix composite material. Powder of Al2O3 was used as ceramic material after had been pressed by different pressures (58 Mpa, 117 Mpa and 176 Mpa) in metallic mold. The sintering process has been preformed at 1200oC for two hours. After that, the porosity percentage has been measured and the samples were heated to 700oC and then immersed in the molten pure aluminum and (Al-2.26% Mg), and heated to about 1000oC for half an hour. Then, the samples were cooled to 650oC. Microscopic tests and x-ray diffraction analysis has revealed zones with different hardness and with different structures. Moreover, the results showed that the adhesion between the ceramic matrix and the deposited metal depends on the molten metal type and the percentage of magnesium content of aluminum.
