Investigation of the structure and impact-abrasive wear resistance of coatings of the Fe–C–Cr–Mn–Si system, additionally alloyed with nitrogen

Abstract

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.
