Thermally sprayed Fe-based coatings could be applied in conditions ranging from almost solid to complete molten droplets. While spraying under atmospheric conditions the oxygen content in the coating alters also in a wide range depending on the spray parameters and the portion of molten phases in droplets (1, 2). Using a Vacuum-Plasma- Spray-System (VPS) Fe-based alloys can be sprayed with high portion of molten phases without oxidation. This fact could be also used for controlled alloying of Fe-based spray materials with nitrogen during as so-called Reactive- Vacuum-Plasma-Spraying (3). The improvement of wear and corrosion resistance of the coatings produced of Febased alloys could be achieved by addition of nitrogen because of the formation of dispersed vanadium-nitride.
