Microstructure and the Wear Mechanism of GrAln-Refined Zn-Al Alloy during Dry Sliding AgAlnst Steel Disc
The low-titanium aluminum alloys produced by electrolysis were prepared and the effects of titanium elements on microstructure and wear resistance of Zn-Al alloy were investigated. The tested results showed that addition of titanium by electrolysis is an effective way to refine the grAln size of Zn-Al alloy. As the titanium content is O. 04 wt％ , the grAln size becomes to be a minimum value. The wear resistance is also improved with the decrease in the grAln size. This can be attributed to the grAln boundary strengthening of ZM8 alloy. SEM photomicrographs of the worn surfaces shows that wear mechanism of ZM8 alloy with and without grAln refinement is similar. The grAln-refined samples of the alloy exhibited a more stable friction coefficient than the untreated ones under the same test conditions.
