Microstructures and properties of plasma surfaced Ni25 and Fe304 layers prepared on nodular cast iron substrate were investigated. The study showed that the interface boundary existed between the layers and substrate. Compared with typical microstructures of welded joint, the similar columnar grains in the layers perpendicular to the interface line were observed, which were hardly seen in the plasma sprayed coating. The conclusion could be drawn that the bonding between the Ni25 and Fe304 layers and nodular cast iron substrate belonged to the metallurgical cohesion. The XRD analysis showed that the metal compounds such as Ni4B3，Cr7BC4，γ-(Fe, Ni) and Cr7C3were found in the layers. The study demonstrated that the layers had proper strength and hardness to repair the surface defects of the nodular cast iron.
