Dry Sliding Wear of Particle Reinforced Aluminum Composites: Review and Discussion

The achievements about the dry wear performance of particle reinforced aluminum (PRA) for last years were reviewed, and the effect of the different tribological parameters on the wear performance of PRAs were analyzed. In general aluminum or alloys mixed with hard ceramic particles can improve obviously the wear resistance. However, under particular conditions, the wear performance of the PRA is similar to or lower than its matrix alloy. Furthermore, conflicting results regarding the effect of the tribological parameters on the wear performance of PRAs were noted. It is shown that these parameters are releted and affected each other, and considering a parameter independently will result in wrong. In order to achieve the optimization of PRA metal couples all kinds of the parameters must be considered simultaneously.
