Abstract

Carbides are used as a raw material for the manufacture of hard alloys, disperse reinforced alloys, wear-resistant coatings, and other. They are produced at lower temperatures, for a shorter period of time of isothermal retention and wherein using-explosive-proof atmosphere. According to the method AC current of industrial frequency is allowed through a revolving layer of pre-prepared disperse material containing metals or oxides and graphite in the required ratios. The current parameters are adjusted within the required boundaries to effect a heating process up to the temperature of isothermal retention. In the process are used active reagents in gas microdischarges between the particles of the disperse medium, being in continuous movement, in the furnace space, wherein inert atmosphere is maintained by letting of argon gas with a pressure of 0.01-0.02 MPa. 1 claim
