FIELD: metallurgy.
SUBSTANCE: procedure consists in vacuum heating items in plasma of nitrogen of higher density. Plasma of nitrogen of higher density is generated in toroid region of electron motion formed with crossed electric and magnetic fields. Under effect of magnetic field created with two cylinder magnets one of which is hollow, electrons move along cycloid closed trajectories.
EFFECT: intensified item nitriding, increased contact durability and wear resistance of strengthened layer.
