摘要：In this work, B4 C porous ceramics reinforced alumium composite was fabricated by the sponge impregnant method and pressureless infiltration technique. The wettability of aluminum on B4 C, the component and the wear resistance of the composite were studied.The result indicates that the infiltration temperature is determined 1200 centigrade and there are mainly Al, B4 C, Al3 BC, no AL4C3 in the experimental composite, the wear resistance of B4C/AL composite is 25 to 30 times higher than that of the alumium.
