FIELD: metallurgy.
SUBSTANCE: method includes chemical preparation of a surface, heating of items by submersion into a hot heated liquid medium for pressure working and thermal treatment. Products are heated serially in a liquid medium in the form of two melts of chlorides of different compositions, besides, in the first one - with a low temperature within 450 -550°C, and the second one - with heating up to 700 - 800°C for performance of thermal treatment of items.
EFFECT: performance of serially different treatments while increasing efficiency and reducing power inputs, expanded assortment of processed items.
