Abstract

In this study, the effect of composition segregation on the wear resistance of high aluminum zinc-based alloy is investigated. The test results show that the improving wear resistance is due to a combined action of α and η phase. The rich solid solution of α−Al has higher strength and load bearing capability than of η phase. Under the action of the sliding friction, the hard α phase was protruded from matrix and acted as a loading phase. The η phase helped to act as a type of natural lubricant in sliding wear situations. Meanwhile, the iron transferred from the steel ring to block and forced to the recess continuously, which forms a thin protective film at the contact surface, then the load bearing capability of the test alloy would be improved.
