Wear behavior of aluminum metal matrix composites: A Taguchi approach

摘要

In the present investigation wear resistance of Aluminium Matrix Composites (AMCs) were studied using Taguchi analysis. Al-Si-Ce alloys and Al-Si-Ce-Gr AMCs were casted using stir casting metallurgy techniques and the castings were T6 heat treated. Cerium was added from 0.15 wt% to 0.3 wt% and Graphite of 4 wt% was added as reinforcement in the manufacture of AMCs. The Taguchi analysis was conducted with two different speeds and loads ie 100 rpm to 500 rpm and 10 N to 50 N. From the analysis, it was found that at higher speed and lower load wear loss and coefficient of friction was minimum in all the investigating alloys and composites. Maximum wear loss was observed at lower speed (100 rpm) with highest (50 N) load.
