FIELD: processes and equipment for thermal treatment of machine parts.
SUBSTANCE: method comprises steps of subjecting machine parts to cold treatment in liquid medium, for example in liquefied nitrogen in temperature range (-150°С)- (-269° С) and simultaneously subjecting parts to action of electro-hydraulic shocks.
EFFECT: improved wear resistance of machine parts, die and metal cutting tools.
