Study on Microscopic Organization and Structure of VC-WC-Fe Surface Composites

The microscopic organization and structure of iron-base surface composites reinforced by VC ceramic grains from in-situ production and adding WC ceramic grains were studied by SEM and XRD. The results show that WC and VC can dissolve mutually in according to their content. It will be beneficial to increase the bond strength between reinforcements and matrix. And it can greatly increase resistance to impact and wear of surface layer.
