Special features of the formation of the structure and properties of plasma-powder coatings of 250Kh15G20S are investigated. The effect of additional alloying of the coating with nitrogen by adding nitrided ferrochrome to the filler powder is considered. The effect of the deposition conditions and of the chemical composition of deposited metal on its hardness and impact-abrasive wear resistance is described.
