FIELD: heat treatment processes, namely treating articles with use of highly concentrated energy sources, possibly surface quenching of articles.
SUBSTANCE: method comprises steps of heating surface of part till quenching temperature by means of plasma electron flux generated with use of dependant high- current diffusion charge; further sharp cooling of part surface in argon flow at rate exceeding critical quenching rate of steel.
EFFECT: enhanced efficiency, shortened time period of process, simplified design of equipment, high quality of quenched part.
