Feasibility Study on Tribology and Surface Morphology Characterization of Hybrid Composites

Objectives: To investigate the tribological behaviour of aluminium hybrid composites. Aluminium alloy (LM 25) is utilised in aerospace and defence industries. Its wear properties are further improved to increase lifespan components used these sectors. Due their ability resist wear, graphite silicon carbide often manufacture machine tools. The objective identify parameters LM 25 alloy. It was examined after stir-cased strengthened with various weight ratios. Methods: dry sliding for alloys containing 2, 4, 6 wt.% a fixed 2 investigated using stir-casting These process included loads 15, 30, 45 N, speeds 0.55, 1.10, 1.65 m/s, distances 333, 666, 999 m. Findings: According test results, overall loss SiC-reinforced composites less compared both unreinforced Al/Gr composite consisting 4% SiC 2% Gr significantly base Novelty: novelty this study induce brake disc made an Al wear-resistant SiC/Gr particle-reinforced committed its surface. role tribology determining material shown be important controlling removal.
