Article Preview

In order to improve corrosion resistance of widely used carbon steels, self-fusion Ni60 alloys coating was prepared by free-spraying and induction heating, taking 45 steel as substrate. The microstructure and corrosion resistance of the coating and the elements diffusion cross the interface between the coatings and the substrate were analyzed. The results indicate that Ni60 coating free from cracks is obtained by free spraying and induction heating. The microstructure of the Ni60 coated substrate consists of top surface, intermediate layer, dendritic crystal zone and lamellar zone from outside to inside. The corrosion resistance of Ni60 coatings is markedly superior to that of the substrate in acid and alkali solution, and surpasses stainless steel in reductive and alkali solutions
