Abstract

Aluminium alloy based metal matrix composites (AMMC) are widely used for sliding wear applications because of their excellent wear resistant properties. AMMC are fabricated using method liquid state fabrication. It was found that stir casting is an economical method to fabricate AMMC. In the present work, aluminium alloy2024 reinforced with various percentages of Silicon carbide particles (2, 4, 6 wt %) were prepared. At first the stir casting setup was prepared as per the requirement. The objectives of this research work are the fabrication and characterization of Al-2024 with Silicon carbide AMMC which was fabricated using stir casting process and improving mechanical properties. The purpose of this project was to study the wear behavior of Al2024-SiC composite manufactured by centrifugally atomised casting enrooted with varying SiC reinforcement compositions and sintering temperatures. Four different samples (SiC reinforcement compositions 0, 2, 4 and 6 Vol. %) of the composite were made by mixing, cold pressing and sintering. The change in hardness values were noted and studied. Then SEM analysis of the samples was done to study the phases present and their distributions along with idea of composition as well as Wear. Hardness and Wear studies were carried out to judge the surface mechanical properties of the composites prepared
