Effect of Counter Surface Temperature and Load on the Transition from Mild to Severe Wear Behavior of Al-Si-SiC_p Composites in Reciprocating Conditions

Abstract:

In the present paper, the effect of counter surface temperature and load on the transition from mild to severe wear of A319/15%SiC_p, A336/15%SiC_p, and A390/15%SiC_p composites have been reported. Composites were produced through stir casting route. Adhesive wear behavior of composites was studied under dry reciprocating conditions using indigenously developed reciprocating friction wear test rig conforming to ASTM standard G133-05. It was found that increase in counter surface temperature increases wear rate and depending upon the load and type of composite mode of wear changes from mild oxidative to severe metallic wear noticed. At 120N load, the critical transition temperature for all the three Al-Si-SiC_p composites was found to be 350°C. SEM study of wear surface and wear debris was conducted to analyze the mode of wear and operating wear mechanism. Severe wear was characterized by massive plastic deformation and gross material removal while the mild wear was found to be associated with delamination and scoring as main wear mechanisms responsible for material loss.
