Evaluation of Wear Rate of Aluminium Hybrid Composites Fabricated through Stir Casting Technique

Abstract:

The Al2014 alloy is extensively used as a structural material in aerospace industry and also it is proving to fit as wear resistant materials especially in sliding wear applications. In the present paper, the wear analysis of hybrid Al-MMCs utilising Al2014 alloy as matrix and Silicon carbide (SiC) / Graphite (Gr) particulate reinforcements was studied by changing load, speed and percentage reinforcement. Al2014+10%SiC composites and Al2014/(5%SiC+5%Gr) were prepared using liquid state processing. The wear test is carried out by using pin on disc with sliding speeds range from 0.84-1.67m/s and loads from 25-75N and sliding distance of 1000m.The outcomes demonstrated that the connected load had positive effect on wear rate while sliding rate indicates reverse movement on wear rate. The incorporation of SiC and Gr is observed to be significant on account of self-lubricating impact of Gr and resistance to material plastic flow due to SiC reinforcement.
