A complex of special properties of materials and a threshold of their working temperatures which is frequently limited 500–550°C define the level of modern technological development and, first of all, for nuclear-industrial plants. The alloys on the basis of iron are the most widespread kind of constructional materials, and therefore an increase of their special properties (high-temperature strength, corrosion stability, durability and other characteristics) is of great value. The ionic beams with a low energy (300–1,500 eV) which can change the structure and the properties of a target, in particular iron and its alloys were used for the solution of these problems in the present work. In this work theoretical and experimental results of the research of the process of impact interaction of the ionic beams with iron are also given. The properties of a iron surface with the help of modern methods of physical and chemical analyse are investigated. The opportunities to produce new surface properties of iron using the ionic beams are shown. On the basis of the results obtained the supplementary work directions are analyzed.
