INTERRACE DLSSIPATING ENERGY AND WEAR RESISTANCE OF FIBER REINFORCED METAL MATRIX COMPOSITES

The effects of the interface in alumina short fiber reinforced aluminum alloy composites,which were manufactured by squeeze casting,on the wear resistance of the composites are studied,The results of the study indicate that the fiber combines with aluminum alloy matrix well in the complesites and has reinforcing effect on aluminum alloy;and that the interface in the composites can hold back crack propagation,and the composites possess excellent wear resistance. The alloy elements in the matrix are favourable to forming good interface to improve wear resistance of the composites.
