This study evaluates the base mechanical properties of Hastelloy C-276, WC-Co, and Cr3C2-NiCr coatings produced by HVOF spraying at angles ranging from 60° to 90°. Examinations and tests were conducted to characterize changes in microstructure, density, hardness, wear resistance, surface roughness, and deposition efficiency based on spraying angle. Only minor spray-angle dependencies were found for base mechanical properties, although thickness, roughness, and deposition efficiency varied greatly.
