POWDER METALLURGICAL PROCESSING AND CHARACTERIZATION OF GRAPHITE PARTICULATE REINFORCED COPPER MATRIX COMPOSITE

Abstract

Composite materials are having greater demand in all the fields. In electrical components like motor brushes copper based composite material has more benefits. Graphite particulate reinforced copper matrix composite has been made using powder metallurgy in different weight fraction. Microstructure study has been done using optical microscope. A microscopic figure shows the distribution of graphite particulates in copper matrix. Brinell hardness test has been done to study physical properties of composite material. It has been resulted that hardness of composite material is decreased as graphite particulates percentage increased in copper matrix.
