FIELD: metallurgy.
SUBSTANCE: invention relates to thermal treatment of machinery and mechanisms field. For increasing of wear resistance of forming and metalcutting tool method includes treatment by cold in medium of condensed gas at temperature -150…-269°C with simultaneous influence on details by impact mechanical oscillations with amplitude up to 3 mm and impact electromagnetic field with intenseness up to 250 kA/m.
EFFECT: complex influence by cold, impact oscillations and impact electromagnetic field provides essentially increase effectiveness of machinery treatment at simultaneous reduction of power inputs and production cost of magneto- impact unit.
