The derivatives of this conceptual approach are the following main provisions: corrosion resistance, etc.). 2. The presence of a defect concentration gradient over the thickness of the film material is an additional driving force of diffusion mass transfer in volume (the phenomenon - by the mechanism of "defect-gradient-induced diffusion"). 3. Critical values ​​of ion energy are established, at which the dominant diffusion mechanism changes during ion bombardment of nanosized compositions - from the mechanism of defect-gradient-induced diffusion to the radiation-stimulated mechanism. 4. Variation of defect-gradient distributions, distributions of special structural-phase states and mechanical stresses by thickness provides new properties. The work corresponds to the world level. The results are of practical value for increasing the corrosion resistance of nanowick functional-gradient film materials in many interdisciplinary fields - medical materials science, theoretical and biomedical engineering, production of computer base, applied physics and solid state chemistry micro-, opto-, cryo-, magneto- and nanoelectronics), etc. Product Description popup.authors Vasyliev Mykhailo O Vladymyrsyi Ihor A Orlov Andrii K.
