Effect of Heat Treatment Variables on the Abrasive Wear Behaviour of Al-6061 Alloy and Al 6061-SiC_P Composites Using Taguchi Technique

摘要

In this paper an effort has been made to study the effects of ageing variables on the abrasive wear behavior of Aluminium 6061 alloy and Silicon Carbide particulate reinforced Aluminum 6061 Composites. The composite material was prepared by using stir casting technique. The as-cast material was heat treated by a method called homogenization annealing to obtain uniform grain size. Fractional factorial experimentation was carried out using four parameters namely volume fraction of reinforcement, solutionizing time, ageing temperature and ageing time at three different levels. The results show that the predicted values for abrasive wear loss were in close agreement with experimental results. And moreover the volume fraction of reinforcing particles was found to be most influential parameter in affecting the wear loss of the materials followed by the ageing temperature and all the other parameters and their interactions.
