DEVELOPMENT OF AL-SiC COMPOSITE FOR AUTOMOBILE AIR COMPRESSOR PISTON

Mechanical Engineering

Self-propelled machines which includes whole the automobile industries are working for lighter the weight and strengthen the body of machines. Automobile industries are also using material substitution for to build lighter weight, and fuel efficient engines, offering better properties materials of engine components. The piston is a "heart" of the engine and its working condition is the worst one of the key parts of the engine in the working environment. So it is very important for structural analysis of the piston with the acceptable composite material as replacement of now-a-days materials. The present work describes that Al composite as possible alternate materials with its unique capacity to give required properties for engine heart ‘piston’. Al MMC are prepared by powder metallurgy and various casting techniques. In this paper a composite is developed by stir casting process by using Aluminum alloy with other Nano particles and substitute sintering operation at 600°C temperature for one hour. Mechanical Tests like microstructure, Hardness, crushing load, surface roughness, etc. are conducted and final analysis on piston will be done.
