| Abstract: | A new kind of thermal spray powder WC-12Co with a small amount of nanostructured particles used in corrugated roller was produced by the agglomerating, sintering and crushing technology. The corresponding coatings were deposited by high velocity oxy-fuel spraying （HVOF）. The properties of bond strength, micro-hardness, porosity and fracture toughness and per pass thickness of the coatings were investigated; Phases of the feedstock powders and the coatings were analyzed by XRD. The characterizations of spraying feedstock powder and the microstructure of cross-section of coating were analyzed by OM. The results indicated that the spraying power exhibits sphere and has good flow rate, only a little of WC decomposed during spraying. Meanwhile, all the coatings exhibited excellent performance under various HVOF spraying parameters, such as high bond strength, micro-hardness, high depositing efficient, compact structure and moderate toughness, which has the similar performance compared with the coating prepared by the imported special powder used in the corrugated roller. |
