INVESTIGATION AND ANALYSIS OF PISTON BY USING COMPOSITE MATERIAL

COMPOSITE MATERIAL

An Internal Combustion Engine is that kind of prime mover that converts chemical energy into mechanical energy. The fuel on burning changes into gas which impinges on the piston and pushes it to cause reciprocating motion. The reciprocating motion of the piston is then converted into rotary motion of the crankshaft with the help of connecting rod. Metal Matrix Composites (MMCs) have evoked a keen interest in recent times for potential applications in Aerospace and automotive industries owing to their superior Strength to weight ratio and high temperature resistance. Composite materials are gaining importance for their advantages including low cost, ease and simplicity of operation. Composites containing hard oxides (like SiC) are preferred for high wear resistance along with increased hardness, improved corrosion resistance and high temperature oxidation resistance as compared to alloy and pure metal. Composite coating is used for the purpose of wear resistance. With increasing availability of micron-sized particles of SiC, there is growing interest in the electrolytic and electro less co-deposition of these particles. In this work, material composition test, hardness test, of such composite coatings are carried out. The effect of particle size and number of particles suspended is reported. SiC Composites have been deposited on Aluminium by casting process. The resulting castings are studied using scanning electron microscopy and hardness tests. The piston is modeling using Pro-E modeling and analyzing using ANSYS simulation software for Aluminium (Pure) and Aluminium-SiC and the results were discussed.
