The surface of a porous tungsten carbide pseudo-alloy of the WC–WCoNiFe system has been modified by a pulsed electron beam and the method of combined electron-ion-plasma processing, which includes vacuum arc deposition of the VT1-0 titanium alloy film (1 μm) and subsequent pulsed electron-beam processing of the coating/substrate system. Optimal modes of pulsed electron-beam processing were found depending on the energy density in the pulse (40−65 J/cm2) and the pulse duration (150−200 μs). It is shown that the electron-beam surface processing of the material of this class under optimal conditions of electron-beam processing makes it possible to increase the microhardness of the surface layer by 15% compared to that of the initial material. Using methods of x-ray phase analysis, it was revealed that the increase in the microhardness was due to the formation of the W2C phase in the surface layer and the decrease in the amount of the binder (WCoNiFe). It is concluded that the combined electron-ion-plasma processing of the porous tungsten carbide pseudo-alloy of the WC–WCoNiFe system makes it possible to form a modified layer with a minimum number of pores and cracks on the surface.
