Abstract:
In reeent years, ZA alloy, as a result of its exeellent casting performanee, mechanieal properiesand wear resistanee, has become one of the hot spot on ally study. This paper deals with the elfeet of Silieonon the mierostructure, mechanism property and dry sliding wear of Zn-75 Al Alloy by using OM, TH700 Vick.ers hardness tester, eleetronie universal testing machine and MMU - 10G wear test instrument. The resultsshow that addition of silieon to 2n-75Al resulted in the formation of euteetie silieon phase. lt is evenly distribu.ted when silieon content in alloy is less than 396 . However, lt becomes larger, exhibits a kind of micro-segre.gation , and precipitates a small amount of irregularly shaped primary silieon phase when silicon eontent in al.loy is more than 3% . WVith the inerease of silicon content, the Vickers hardness of the alloys inereases, the e.longation deereases , while the tensile strength of the alloys inereases firstly and then deereases, and it is maxi-mum when silicon content is 396 : the eoelieient of frietion and volume loss of alloy deereases firstly and thenincreases, and the wear resistanee of alloy is best when silicon content is 3%
