Abstract:
This study deals with the effects of ZrSiO۴ particles addition on the abrasive wear behavior of aluminum based metal matrix composites. The Al-A۳۵۶/۵ vol% ZrSiO۴ specimens were prepared by the injection of particles in the as-received form or Al-ZrSiO۴ milled composite powder. The injection of composite powder caused remarkable improvement in ZrSiO۴ distribution within the Al-۳۵۶ matrix alloy. The composites were fabricated by two different routes: semisolid-liquid state (SL) and liquid-liquid state (LL). According to the results, a better distribution of reinforcing particles was observed when the stirring was conducted in the semisolid state. Based on the wear test results, the composite with ball-milled Al-ZrSiO۴ particles (A۳۵۶/(Al-ZrSiO۴)cp ) processed in the SL state exhibited the highest wear resistance in terms of wear rate and friction coefficient. The worn surfaces of specimens were examined to identify the possible mechanisms.
