| Abstract: | In order to control the shape and distribution of hardening phase in plasma surfacing deposit, a longitudinal DC magnetic field was applied during plasma surfacing of nickel-based alloy Ni60. Hardness, wearing resistance, microstructure and phase constituent of the plasma surfacing layer were investigated. It was revealed that the hardness and wearing resistance of the Ni60 plasma surfacing layer could gotten significantly enhanced through introducing magnetic field. The mechanical properties of the surfacing deposit were optimal when magnetic field current is 1 A. The metallurgical analysis showed that the microstructure of the Ni60 plasma surfacing layer was mainly composed of γ solid solution and some hardening phase particles such as Cr7 C3 with an application of the magnetic field. |
