Experimental Analysis on Sliding Wear Behaviour of Aluminium-6063 with SiC Particulate Composites

Abstract

One of the most common problems encountered in many industrial products and its applications is wear. The purpose of this experimental research article is to analyze the wear behaviour of Al-6063 based SiC composites using pin on disc testing machine. In this present investigation there are nine different samples of Al/SiC composites with 5%, 7% and 9% volume of SiC were prepared through stir casting process. The sliding distance of 500 meter and the load 10 N were applied for wear testing of these prepared samples. From the experimental results, it was observed that the sliding velocity is greatly affects the wear rate and on increasing the sliding velocity the wear loss increases. It was also found that the wear loss decreases by increasing the amount of reinforcement element. Scanning electron microscope was used to examine the wear surfaces and found that the micro and transverse cracks, mild and severe wear occurred in the composite worn surfaces and wear structure of the composites.
