This paper presents a comparative study of the microstructure, phase properties, hardness, and wear resistance of high-pressure HVOF sprayed coatings. The layers were produced by the JP-5000 method using WC12Co and WC17Co powders varying in size distribution and morphology. Spray parameters were statistically evaluated using a design-of-experiments approach in order to optimize wear resistance as well as deposition efficiency, carbide grain size, and degree of oxidation. Paper includes a German-language abstract.
