Two and more materials with significantly different physical and chemical properties are engineered to form a composite material. The properties of these materials remain separate at microscopic or macroscopic scale even when the structure gets finished. The materials we get after finalizing the composite have high density and high strength. They are used when we need light weight and high strength materials such as in the aspects of industrial and commercial fields in aircrafts, ships , common vehicles and different other engineering applications. Such type of materials are formed by adopting stir casting technique on Al7075 by adding reinforcements of Al2O3 in the form of nano and micro particles at varying wt. %. In present study Al7075-Al2O3 metal matix composite developed in three different compositions of micro and nano particles. The Fabrication of composite are carried out by liquid metallurgy route via stir casting technique. Casted composites machined to make the samples microstructure analysis and sample for pin-on-disc machine according to ASTM standard. This paper also includes information about tribological tests. These tests were carried out following Taguchi Method for different combinations and sizes of reinforcements, the various parameters used are Load, Sliding distance, Sliding velocity. Mechanical testing of composites are also done on various machine and equipments to find the effects of reinforcement weight percentage and size of reinforcements. It is found that density of the composites improved than the matrix alloy as the percentage filler contents increased the improved of density of composite. SEM images of micro and nano composites reveal that agglomeration of particles increases with increasing wt. %age. . In future scope some MMCs can be manufactured by using diffrent manufacturing techniques like powder metallurgy etc. and results can be compared with stir casting technique and with the base alloy.
