The microstructure of Al2O3/Mo composite was analyzed and the wear behavior was tested. The analysis results of wear data and wear morphology show that the amount of density first increases and then decreases gradually, but hardness increased with the increasing of the volumn fraction of Al2O3. There is some degree of reduction on the wear produced by the process of cutting, plowing. When the Al2O3 volume fraction is 3%, the specific wear rate of composites increases gradually with the particle size decreases. However, at higher Al2O3 volume fraction (5%, 10%, 15%), the specific wear rate first increases and then decreases with the increasing of abrasive grain diameter. The wear loss increases with the increase of the load, while there is no influence on the order. On the same load, the wear loss shows a declining trend with the continuous increase of Al2O3 content, but the speed is slower.
