摘要

Metal matrix composites are widely used in different applications where light weight materials with exceptional mechanical characteristics are sought. These applications include aerospace, automotive, and other industries. In the current investigation, wear process parameters optimization of Al7075-ZrC composites employing Taguchi approach has been carried out. Al7075 alloy was chosen as the matrix material. Zirconium carbide was chosen as reinforcement material. Stir casting approach was employed to produce Al7075-Zirconium carbide composites. The Zirconium Carbide particulates were varied in terms of 6, 9 and 12%. The developed composites were subjected to hardness and wear tests. The wear tests were performed employing Taguchi’s methodology. The importance of variables on the wear during the process of wear was determined. Scanning electron microscopy analysis showed that Zirconium carbide particles were uniformly dispersed throughout the aluminium matrix. The incorporation of Zirconium Carbide particles into Al7075 matrix enhances the BHN of the composites. The BHN values of Al7075 alloy and the Al7075 + 9% zirconium carbide composites are 77.25 BHN and 93.37 BHN, respectively. The Brinell Hardness Number shows a 20.86% increase from the alloy to composite. The ANOVA findings for wear showed that the weight percentage has the highest level of significance, contributing 44.26% to the overall outcome. This is followed by load, speed, and sliding distance. The confirmatory results show that the maximum error attained is 3.54% which is within the acceptable limit i.e. 8%. The examination of SEM images of the worn-out surface of Al7075-Zirconium Carbide composites demonstrated the existence of worn-out particles. The delaminated area in the Al7075-9%ZrC composites is less compared to that of Al7075 matrix.
