Abstract

A functionally graded WC-Co/Ni composite (FGWC) is successfully fabricated. The FGWC is composed of WC-Co layer, transitional layer and Ni layer. The transitional layer with graded variation of WC particles and Ni phases serves as the buffer zone to relax thermal stress. Liquid phase sintering has considerable influence on the forming process of the transitional layer. The microhardness values of the transitional layer gradually decrease along the direction of WC-Co layer to Ni layer.
