In this paper we briefly describe the principles and technological feasibilities of three methods of electron beam evaporation of materials: direct electron beam evaporation, activated reactive electron beam evaporation and electron ion evaporation. The advantages and drawbacks of electron beam vapour phase technology are discussed with respect to the deposition of corrosion-resistant, heat-resistant and wear-resistant coatings. Examples of electron beam equipment for deposition of these coatings in continuous and batch operation are given. It is emphasized that the electron beam evaporation of metallic and non-metallic materials should be considered as the most physicochemically precise set of methods for designing composite coatings of dispersed or laminar type, which cannot be deposited by other methods. The effect of structural parameters and interphase interactions on the strengthening and plasticity of coatings of the dispersion-strengthened type is studied. Further progress in the creation of protective coatings using electron beam evaporation should be based on the development of composite materials with special properties and on the simultaneous improvement of electron beam equipment and reduction in its cost.
