Abstract
In this work, B4C porous ceramics reinforced alumium composite was fabricated by the sponge impregnant method and pressureless infiltration technique. The wettability of aluminum on B4C, 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, B4C, Al3BC , no AL4C3in the experimental composite, the wear resistance of B4C/AL composite is 25 to 30 times higher than that of the alumium.
