FIELD: technological processes.
SUBSTANCE: invention relates to the formation, on steel surfaces, of coatings based on titanium, titanium and aluminum diboride, which can be used in stamping and other industries. Method involves electric explosion of composite electrically blasted 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 diboride powders with a mass equal to 0.5–2.0 times the mass of the shell and a titanium with a mass equal to 0.5–2.0 of the shell mass, formation from the explosion products of a pulsed multiphase plasma jet, its fusion with the surface of the die steel at an absorbed power density of 4.6–4.8 GW/m2, deposition on the surface of explosion products with the formation on it of a composite coating of the TiB2-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 aimed at obtaining a wear-resistant coating on the surface of the die steel with high adhesion to the substrate at the level of cohesion.
