Enhancement of mechanical properties wear resistance corrosion analysis and mathematical modeling of Cu V Gr L composite using stir casting

Abstract

Nowadays a lot of research works are carried out to improve the strength of materials. In recent days, the usage of pure form of material is reduced due to their poor mechanical and physical properties. In order to enhance the properties of materials, Metal Matrix Composites (MMC) are introduced. MMC plays a major role in the development of new materials. The mechanical properties will be improved with the evenly distribution of reinforcement and reduction in microstructure. Metal Matrix composites are nowadays used in many applications like electronic components, heat sinks, radiators, electronic contact devices, heat transfer applications, casing of jet engines, cylinder heads, liners and brakes in automotive industries. Many new materials are developed for various applications. One of the interesting materials is copper. Copper is unique for its properties like high thermal conductivity, high electrical conductivity and ductility. The present study includes the preparation and characterization of Metal Matrix Composite. MMCs are normally produced using stir casting process, powder metallurgy, liquid metallurgy and squeeze casting process. Among these, stir casting is one of the most widely used methods used to fabricate MMC by the addition of reinforcement particle along with copper matrix. From the experiment it is found that the enhancement of copper in its mechanical and wear behaviour can be attained by the addition of vanadium and graphene particles as reinforcement. The copper matrix is dispersed with vanadium reinforcement of various weight % like 0%, 0.5%, 1.0%, 1.5% and 2% respectively. Vanadium is known for its hard, silvery-grey, ductile and malleable behaviours. When vanadium reinforced with copper, it resists the formation of grain boundary cracking. newline newline newline
