Synthesis and Characteristics of Aluminium Metal Matrix Composites Using Al2O3 and SiC as Reinforcement Materials

Abstract

Aluminium metal matrix composites have been successfully developed since last forty years. In the e present investigation Al2O3 and Sic have been used as reinforcement with aluminium – copper ally as matrix material. The composites were prepared with varying amounts of Al2O3 and silica. Corrosion studies were carried out using a standard salt spray fog corrosion testing apparatus confirming to ASTM standard B117 specifications. The results of the investigation are presented and discussed
