FIELD: machine building.
SUBSTANCE: according to invention steel items are nitrided in glow discharge by means of vacuum heating in plasma of nitride of increased density; further, items are quenched. Also, plasma of nitride of increased density is generated in a circular region of rotation of electrons caught with magnetic field, power lines of which are parallel to treated surface. Notably, electron cloud is maximally localised at the part-cathode.
EFFECT: intensified process of nitriding, increased contact service life and wear resistance of strengthened layer.
