Mechanical Properties and Triobological Behavior of Stir Cast Al-6063 Alloy Based Hybrid Composite

Abstract

India is one of the developing countries that need to face the many challenges in automotive industry. In industries usage of heavier materials are replaced by aluminium alloys because of its good properties. The objective of this work is investigating the influence of quarry gravel powder (QGP), silicon carbide (Sic) and fly ash (FA) particles of fraction percentage on the mechanical properties and wear behavior of Al6063 based alloy metal matrix composites. The abrasive ceramic particles, fly ash and gravel powder reinforced in the metal matrix are the cause of improvement in mechanical and tribological properties of the materials. The al 6063 metal matrix hybrid composite consist of 4 wt%, 6 wt%, and 8 wt% QGP-SiC–FA respectively was processed by using stir casting technique procedure. Tribological Wear behavior of the developed hybrid composites was characterized at different loads, sliding velocities and distances using pin-on-disc method. The experimental results are discuss that the applied load and reinforcement of wt% are the major parameters influencing the specific wear rate for all samples, followed by weight fraction of reinforcement, sliding velocity and sliding distance.
