Abstract
Samples of CeO2-WC- Ni base alloy coating were made on 45# steel substrate by vacuum melting. The influence of CeO2addition on microstructure of longitudinal section of coatings, elements diffusion at the junction, and WC morphology and distribution was analyzed by scanning electron microscopy and energy dispersive spectroscopy. The results showed as follows: with 0.75% CeO2addition, the coating best combined with the substrate and had least pores, cracks and other defects; CeO2played a significant role in promoting the diffusion of alloying elements (mainly Fe, Ni diffusion at the junction); CeO2changed the morphology and distribution of WC hard phase in the coating, making it small, uniform, and dispersed, and promoting the diffusion between Ni-based alloy and WC in the coating.
