Study on Roller Ring of Steel Matrix Composites Reinforced by WC Particle

Peizhong Feng

Abstract

The WC_p/steel composites roller ring was formed by centrifugal casting,and the microstructure and properties of this composite material were analyzed.It was found that it was fine that the connection of composites surface layer and matrix,and the hardness of the former was kept at 63～65 HRC;there were the dissolving precipitation between WC particle and steel matrix; the maximum thickness of composites surface layer was 3.9 mm;the wear resistance of composite materials was 3 times higher than that of centrifugal casting steel.
