FIELD: machine engineering, possibly surface hardening of articles.
SUBSTANCE: method comprises steps of carrying out bright quenching due to heating and cooling articles in evacuated chamber in argon flow whose rate exceeds critical rate of steel quenching. Heating is realized up to temperature 830°C in glow-discharge plasma of increased intensity created between part and screen due to hollow cathode effect.
EFFECT: improved quality of quenched articles due to highly uniform heating of their surface at desired temperature.
