In the work, on the example of a coating of a metal-ceramic alloy of 50 vol.% TiC / 50 vol.% (Ni-Cr) of the working part of a die for granulating plastics, the results of the study of the possibilities of using the pulsed electron-ion irradiation method to eliminate continuity gaps in the coating in the form microcracks formed during operation of the die through through the cross section. It has been shown that pulsed electron-ion irradiation makes it possible to restore the integrity of metal-ceramic coatings by filling cracks with a melt of a nickel-chrome binder metal-ceramic composition extending to the surface of the coating of cracks to a depth of more than 100 μm.
