Tribological and Wear Behavior between Aluminum Matrix Composites and Copper Matrix Powder Metallurgy

The tribological and wear behavior of aluminum matrix composites and copper matrix powder metallurgy is debated in the paper based on the experiment between the two materials.The friction coefficient and the friction stability of the two materials demonstrate they are appropriate brake materials for high-speed train.The wear of aluminum matrix composites,which is the common result of spall,adhesion and particle wear,is analysed in the end of the paper.
