Abstract
This paper presents constructions of roller dies have been proposed, which make it possible to produce wire of simple and shaped profiles with a diameter of 0.5 to 12.0 mm. Technological solutions for the production of a hex profile S = 2.2 mm from a billet of hard-to-form alloys AISI 316, AISI 304, Ti3Al5Mo5V of various diameters are shown. To increase the service life of the dies, the rollers made of heat-treated steel of the X162CrMoV12 grade are recommended to be strengthened by applying a functional coating made of WC-10Co-4Cr alloy on the working surface by detonation sputtering followed by melting of this layer with a laser. Studies carried out on the samples showed a sevenfold increase in wear resistance in comparison with similar ones subjected only to the traditional for X162CrMoV12 heat treatment in the form of quenching and tempering.
