Abstract
The present work aims at developing an Aluminium metal Matrix Composite (AMC) with an industrial waste Lime Stone Powder (LSP) as reinforcement, which is available in plenty at no cost. The main objective of the present study is to investigate the effect of four control parameters viz.: load (L), percentage of LSP reinforcement (R), sliding distance (D), sliding velocity (V) on two tribological properties wear rate (WR) and coefficient of friction (CF) of AMC reinforced with LSP. The composites are manufactured using the stir casting process with varying LSP percentages (0%, 4%, 8%, 12%, 16%). The wear test is conducted using Pin-on-disc apparatus. Taguchi L25 orthogonal array design is employed to investigate the effect of the above control parameters on the tribological responses. Analysis of Variance (ANOVA) employment indicates that wear rate depends on sliding distance and load, while the coefficient of friction depends on load and wt.% of LSP. The minimum wear rate of Al-LSP is found to be 0.1952, while the minimum coefficient of friction of Al-LSP determined is 0.0905. To minimize wear rate and coefficient of friction simultaneously, a composite objective function is created using Grey Relational Analysis (GRA).
