This paper discusses the optimization of HVOF spraying parameters for applying WC-Co and WC-CoCr powders. Coatings produced using the optimized parameters are evaluated based on microstructure, microhardness, and porosity. The influence of the processing method used to produce the powders is also considered along with in-flight particle characteristics. Paper includes a German-language abstract.
