Wear Analysis of Surface Composites of AA6063/SIC_p Produced by Friction Stir Processing Using Taguchi Technique

摘要

In present study, the taguchi approach was used to optimize the wear analysis result, owing to easiness and low cost requirement which is depend on the concept of orthogonal array. It uses hit and trial approaches to optimize high complex engineering problems. In this experiment, three variables at three levels were used. Using the anova technique for L9 taguchi model, the percentage contribution of each FSP process parameters on the wear rate and frictional force were studied in this present experimental study. Friction Stir Processed (FSP) Aluminum alloy 6063 is modified with SiC ceramic particulate of 400 mesh size. By using pin -ball-on-disk configuration at a rotational speed of 500 rpm and the normal load is 30N, 40N, and 50 N, the wear properties of modified surface is determined. The modification process is done at a constant tool feed rate of 59, 95 and 124 mm/min and tool rotation speed of 1000 rpm. With the help of optical microscopy, microstructure properties of worn surface are determined. A significant improvement has been observed in microstructure and hardness of the surface composite. The Anova analysis justified that the sliding distance followed by weight percentage of SiC are the most significant parameters in minimizing the wear rate.
