Al Matrix Composites

SiC particulates reinforced with Al matrix composites were fabricated using a thermal spray process. In addition, the dry sliding wear behavior was investigated using various sliding speeds and applied loads. Premixed Al and SiC powder was sprayed onto an Al6061 substrate by flame spraying, and dry sliding wear tests were performed under varying sliding speed and applied load conditions. Wear behavior of the composites were studied using a scanning electron microscope(SEM), X-ray diffraction(XRD) and a surface roughness tester.

Sic Composites

SiC particulates reinforced Al matrix composites were fabricated by thermal spray process, and the dry sliding wear behavior against four different counterparts was investigated under a varying of the sliding speed and the applied load conditions. Al/SiC composites were fabricated by flame spraying, and the dry sliding wear tests were performed using the sliding speed of 0.4 m/s and 0.8 m/s at the applied load of 3 N. Sliding distance was kept at 1000 m for all the tests. Al2O3, ZrO2, Si3N4 and AISI 52100 balls were used as the counterparts. Wear tracks on the Al/SiC composites were investigated using scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX). It was revealed that wear behavior of Al/SiC composites was much influenced by counterpart materials.
