FIELD: metallurgy. ^ SUBSTANCE: procedure consists in positioning part in vacuum chamber, in connecting part to high voltage power source, in vacuum chamber sealing, in generating high vacuum in it, in successive changing it with atmosphere of pure nitrogen, and in generating stable plasma of glow discharge in atmosphere of pure nitrogen by means of high voltage power source and electron flow from tungsten filament arranged parallel to axis of vacuum chamber. Filament heated to temperature 2000-2500C generates flow of electrons. Also flow of electrons is compressed with electromagnetic field, thus, there is produced plasma of glow discharge in form of disk of volume where D is internal diametre of the vacuum chamber, t is length of the tungsten filament. ^ EFFECT: increased wear resistance and fatigue durability of parts of machines owing to ion nitriding. ^ 1 dwg, 2 ex |
