Technological peculiarities of local strengthening of high-strength cast iron

Yu.S. Samotugina

Priazovsky State Technical University, Mariupol, Ukraine

Abstract
A possibility is shown of a considerable increase of abrasive wear resistance of high-strength cast iron in plasma surface treatment with deposition of a strengthened layer of a discrete structure. The extent of increase of the wear resistance depends on the treatment mode, direction of plasmatron displacement and relative area of the strengthened surface.
Keywords: plasma surface treatment, high-strength cast iron, strengthened layer, discrete structure, wear resistance
