摘要：

In this research work, Taguchi's experimental design is adopted for achieving maximum micro-hardness values for AA6061/SiC surface composites fabricated using friction stir processing. This was achieved by optimizing friction stir processing parameters. Three process parameters namely tool rotational speed, tool traverse speed and tool tilt angle with three levels each were chosen to maximize microhardness values. Nine experiments were performed strictly as per Taguchi L-9 orthogonal array. After single pass friction stir processing, microhardness of all the samples were tested on Vickers digital microhardness tester. The obtained results were analyzed with the help of signal to noise (S/N) ratio. The effect of all three parameters on microhardness values was studied. The analysis of signal to noise (S/N) ratio showed that maximum micro hardness was achieved when tool rotational speed, traverse speed and tilt angle were selected as 1400 rpm, 50 mm/min and 2.5 degrees respectively.
