Hardness Behavior of Particle Reinforced Metal Matrix Composites by Centrifugal Casting

Peizhong Feng

Abstract

The surface composites made of steel matrix and WC particles were prepared by centrifugal casting.The hardness change of composite materials was studied.The result showed that the centrifugal casting made the WC particles appear gradient distribution,the hardness of composites displayed gradual lower inward,and the transition zone was strengthened.A math model of the hardness of composites was established by regression analysis.
