Abstract: The surface morphology,microstructure,micro-hardness and corrosion resistance of the laser cladding layer and spraying layer of the Ni60 Ni-based self-fluxing alloy were analyzed and compared.The results show that the surface forming performance of the laser cladding layer was better than that of the spraying layer.The microstructure of the laser cladding layer was mostly in non-equilibrium and sub-crystalline state,and had a strong and tough two-phase microstructure characteristics.The microstructure of the spraying layer was rich in the hard phase of carbides.Both the laser cladding layer and the spraying layer could get a metallurgy bonding with the substrate.Although the average micro-hardness of the spraying layer was higher than that of the laser cladding layer,its distribution was not uniform.And the corrosion resistance of the laser cladding layer was superior to that of the spraying layer.
