Study of parameters influencing hole making by friction drilling of aluminium silicon carbide composites

Abstract

Aluminum Matrix Composites AMC are intended to substitute monolithic materials including aluminum alloys ferrous alloys titanium alloys and polymer based composites in several applications Lack of knowledge and information about utilization possibilities service properties and material producers have hindered the wider usage of AMC Particle reinforced Aluminum Matrix Composites PAMC generally contain equiaxed ceramic reinforcements with an aspect ratio less than about 5 Ceramic reinforcements are generally oxides or carbides or borides Al2O3 or SiC or TiB and present in volume fraction less than 30 when used for structural and wear resistance applications However in electronic packaging applications reinforcement volume fraction could be as high as 70 Aluminum Silicon Carbide particulate Metal Matrix Composite AlSiC Composite with required composition was not readily available and hence a set up was designed and developed to make the castings
