In this study, the comparing investigation between the WC– Co/410ss joint and the FGWC/410ss joint is experimentally studied. In the WC–Co/410ss joint, much c phase is formed because plenty of Fe and Cr diffuse into the molten braze during the brazing process. While little c phase exists in the FGWC/410ss joint due to the isothermal solidification, and an intermediate layer with gradient Ni and Cu that is formed between the braze and the Ni layer, contributes to the intimate bonding of the FGWC and the 410ss. The FGWC is beneficial to relaxing stresses and improving the strength of the cemented carbide/stainless steel joints.
