FIELD: manufacture of metallic objects with inner complex-shape cavities, possibly in different branches of machine engineering for making turbines, optical systems of lasers and so on. SUBSTANCE: method comprises steps of making base with desired constructional strength having in its surface recesses and(or) grooves corresponding to inner size of ready article; filling recesses and grooves with easy-to-remove material; forming laminate outer coating of predetermined thickness by electron beam sputtering; preliminarily applying on base thin layer of easy-to-melt metal or material suitable for creating low temperature eutectics with sputtered material of outer coating; performing thermal softening for forming envelope with preset stable homogenous structure and with multilayer or gradually changing composition; removing easy-to-remove material by sublimation at heat treatment. EFFECT: possibility for applying coatings with necessary thickness, with desired physical and mechanical properties but with different chemical contents. 3 cl, 3 dwg, 4 ex
