Elevated Sliding Wear Characterization of Al/SiCp Composites

Abstract

This study was to aimed to investigate on the sliding wear behaviors at both ambient and elevated temperatures in Al/SiCp composites fabricated by the newly developed duplex process. Wear test using wear tester of pin-on-disc type was carried out under the conditions of load 100N , velocity 0.64m/s, distance 4000m. The sliding wear behaviors under the conditions of ambient temperature, 200°C and 200°C-Ar gas and microstructures were studied using OM and SEM. The results obtained from this study are as follows; Wear amount decreased with the decrease in particle size. The wear resistance at 200°C-Ar on composites was greater than those at 200°C and room temperature in the as-composites.
