Abstract Ni60A hardfacing alloy, as one of the highest-alloy grades and hardest alloy of Ni-Cr-B-Si alloys, is expected to be used as hardfacing alloy for thrust discs in nuclear main pumps to reduce friction, corrosion and erosion. Since mechanical properties of Ni-Cr-B-Si alloys are very sensitive to their defects and microstructures, heat treatment/remelting methods have been used to eliminate porosity and to modify microstructural heterogeneity. In our previous research, Ni60A hardfacing layer with high micro-hardness and excellent bonding strength has been fabricated onto 0Cr18Ni10Ti austenitic stainless steel using hot isostatic press diffusion bonding technique. However, some… More >
