Wear behavior analysis of aluminium composites using Taguchi approach

Abstract

Every industry, particularly the automotive and aerospace industries, has a constant need for exceptional materials. Aluminium is the most often utilized material in these sectors. Despite the fact the it contains all of the features to some level, there is a continuing desire for alternative materials. In the automotive industry, friction stir welding represents a huge step forward. In this present study, Stir casting was used to manufacture Al-based metal matrix composites with 9% of TiC particles and 2% of MoS2 as reinforcement. The applied force, sliding velocity, and sliding distance are used as input parameters, while the wear rate is the response. The L27 orthogonal array of Taguchi technique is used to study the relevance and contributions of factors on wear behavior and a statistical plot are used to determine the connection between parameters. Weight percentage of TiC and MoS2 are found to be the most contributing parameter to minimize the wear rate (30.12×10-6mm3/m). Furthermore, sliding velocity and applied load are observed to be the reasons for the increment of wear rate of the optimum composite. Statistical plots are verified that the travel distance is the influencing parameter to minimize the wear rate.
