METHOD OF APPLYING THE WEAR-PROOF COATINGS BASED ON TITANIUM CARBIDE, TITANIUM AND ALUMINUM ON STAMP STEEL

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to the formation of the coatings on the steel surfaces based on titanium carbide, titanium and aluminum, that can be used in stamping and other industries. Method includes the formation of a pulsed multiphase plasma jet using an electric explosion of a composite electrically exploding conductor consisting of a two-layer flat aluminum shell with a mass of 60–530 mg and a core in the form of a mixture of titanium carbide with a mass equal to 0.5–2.0 mass of the shell and a titanium of a mass equal to 0.5–2.0 mass of the shell, its fusion with the surface of the die steel at an absorbed power density of 4.6–4.8 GW/m², the deposition of explosion products onto the surface with formation of a composite coating of the TiC-Ti-Al system and the subsequent pulse-periodic electron-beam treatment of the coating surface at an absorbed energy density of 40–60 J/cm², the pulse duration is 150–200 microseconds and the number of pulses is 10–30.;EFFECT: invention is directed to the production of wear-resistant coatings with high adhesion to the substrate at the level of cohesion.;1 cl, 2 dwg, 2 ex
