Abstrakt: The surface layer of AK5M2 alloy is modified with a Ti film by the vacuum-arc method. The modified samples are irradiated by the method of electron-beam processing using five modes. The dependences of the crystal-lattice parameter and the phase composition of samples of the AK5M2 alloy with surface-modified Ti alloy on the beam energy density during electron-beam processing are determined. The defect substructure of the samples is studied by scanning electron microscopy. The dependence of the coating thickness on the energy density of the electron beam is revealed. The modes are determined, in which the electron-beam energy density is insufficient for the formation of a homogeneous coating. The most rational mode of electron-beam processing is established, in which a homogeneous layer with the least number of surface defects is formed. [ABSTRACT FROM AUTHOR]
