The Influence of Spraying Angle on Properties of HVOF-Sprayed Hardmetal Coatings
Original language description
The spraying angle is one of the deposition parameters that influence the quality of thermally sprayed coatings. In theory, decreasing the spraying angle results in lower process deposition efficiency, whereas the porosity of coatings increases, becominga cause of poorer microstructure and mechanical properties. In this study, the dependence of microstructure together with the basic mechanical properties and wear of WC-Co and Cr3C2-NiCr HVOF-sprayed coatings on the spraying angle was investigated. Foreach coating, the maximum spraying angle was determined that can be used without significantly decreasing coating quality. Based on the changes in properties of coatings and requirements for the process deposition efficiency, a maximum 30° diversion fromthe normal spray direction is recommended for WC-Co and 15° diversion for Cr3C2-NiCr coatings.
