INFLUENCE OF SiC & WALNUT SHELL ASH ON MICROSTRUCTURE AND MECHANICAL PROPERTIES OF AA6082 THROUGH FRICTION STIR PROCESSING

Abstract

Surface modification is a technique used to improve the quality of a surface by making changes to its physical, chemical, or biological properties. In this research, an aluminum AA 6082 Plate is selected, which is been modified by adding small particles of Silicon Carbide and the Walnutshell powder into a groove of 2mm* 2mm width & depth made on an AA6082 plate. Next, designed an experiment using the Taguchi L9 orthogonal array. After that, based on Taguchi design FSP has been performed on the specimens. Additionally, the specimens were subjected to various tests such as Tensile test, Vickers hardness test, Microstructure test. In this study, the Taguchi method is carefully analyze and interpret the results obtained from the experiments are: UTS, Yield Stress, and Vickers Hardness. These properties were studied in relation to three key parameters: TRS (RPM), TTS (mm/min), and the weight of walnut shell ash. By examining the effects of these parameters on the mentioned properties, aimed to gain a deeper understanding of their relationship and how they influence each other.
