Plasma Surfacing

Microhardness distributions, surface morphology, and elemental composition of a deposited layer of a heat-resistant alloy of the type P2M8U steel formed by plasma surfacing in a protective-alloying nitrogen medium are studied. It was established that the surfacing technology and surfacing material allows to obtain a high-quality deposited alloy without cracks, pores, slag inclusions and defects of macro- and microstructure. It has been established that the deposited material is pearlite grains at the boundaries and grain junctions of which are carbonitrides based on iron, tungsten, chromium, molybdenum, aluminum (Fe6 W6 NC and AlN).
