The Study on Preparation of a B₄C/Al Composite Fabricated by the Sponge Impregnant Method

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 AL₄C₃ in the experimental composite, the wear resistance of B₄C/AL composite is 25 to 30 times higher than that of the alumium.
