High-intensity electron beam modification of electroexplosive TiB2–Ni composite coatings is conducted for the first time. The phase and elemental composition of the surface layer of steel Hardox 450 subjected to electroexplosive spraying (EES) of the TiB2–Ni composite coating and subsequent irradiation with a submillisecond high-intensity pulsed electron beam are studied. Electron beam processing (EBP) modes that provide the formation of dense glossy surface layers based on titanium diboride and nickel with a submicrocrystalline structure are revealed. It is shown that EBP of a layer subjected to EES conducted in a melting mode leads to the formation of a surface layer with homogeneous structure and concentration.
