Slurry wear characteristics of zinc-based alloys: Effects of sand content of slurry, silicon addition to alloy system and traversal distance ... with the observations pertaining to the effects of specimen and slurry compositions as well as traversal distance on the slurry wear response of a zinc-based alloy. The composition of the alloy was altered......
wear and delamination with some material transfer of specimen. In addition, the coating presented a better property for alleviating fretting wear. Key words: titanium alloy; micro-arc oxidation... studied in detail. It was shown that the MAO coating shifted the mixed fretting regime and slip regime to the direction of smaller displacement and presented better property of anti- fretting wear......
