Optimization of Wear Behaviour of Al6061 Metal Matrix Composites Using Taguchi Approach

Abstract

The paper's goal is to determine Al6061's wear behavior using Silicon carbide (SiC) reinforcement. When reinforcing is added, aluminum's strength to weight ratio rises, making it the ideal material for applications where a high strength to weight ratio is required. Aluminum-based metal matrix composites are favorable in many industries, including electronics, sports equipment, aircraft, and defense, because of their light weight, high strength, and low coefficient of thermal expansion when reinforced. Under dry sliding wear circumstances, the sliding wear behavior of aluminum matrix composites 6061-SiC has been studied. Stir casting is used to create Al6061 matrix metal and SiC particles with an average size of 44 µm as reinforced particles to create aluminum metal matrix composites (AMMCs). For Al6061, the examined AMMCs had 0%, 3.5%, and 7.0% weight percentage of SiC particles. The usual load of 10, 20, and 30 N, the sliding distances of 1000, 2000, and 3000 m, and the sliding velocities of 1.5, 2.5, and 3.5 m/s were all used in the wear testing. To collect data in a controlled manner, Taguchi orthogonal array techniques were utilized in the Design of Experiments (DOE). To find out how process variables affected composite wear loss, analysis of variance (ANOVA) was created. The findings demonstrated that adding Silicon Carbide reinforcements to an aluminum matrix composite greatly boosts the composite's resistance to wear.
