In the presented paper, investigations on HVOF coatings produced from a new family of powders will be discussed. The influence of microstructure, composition and production methods will be discussed in view of powder properties and resulting coating properties. New boride powders and coatings will be compared with regard to their properties deposition, efficiency, hardness, surface roughness, bond strength, and wear against commercial WC-Co and cr3C2-NiCr coatings. Additionally, improved WC- and CrC-based powders and coatings will be compared with regard to oxidation and erosion resistance.
