چکیده
|
This study deals with the effects of zrsio4 particles addition on the abrasive wear behavior of aluminum based metal matrix composites. the al-a356/5 vol% zrsio4 specimens were prepared by the injection of particles in the as-received form or al- zrsio4 milled composite powder. the injection of composite powder caused remarkable improvement in zrsio4 distribution within the al-356 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-zrsio4 particles (a356/(al-zrsio4)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.
