Abstract:Multimodal WC-12Co coating was deposited on low carbon steel substrate by using JP-8000 HVOF spraying system. The properties of bond strength,microhardness, porosity and abrasive wear of the coating were investigated. The phases of the feedstock powder and the coating were analyzed by XRD. The characterizations of spraying feedstock powder, microstructure and surface micrograph wear surfaces were analyzed by SEM. The results have indicated that the WC does not decompose obviously during spraying and the coating exhibits high bond strength,microhardness and compact structure. Compared with the 316L stainless steel,multimodal WC-12Co coating exhibits excellent abrasive wear resistance.
