Modification of metals by a surface treatment is one of the first problems of modern mate- rials science. The use of ion-plasma technologies for a modification of initial specimens, in particular, by ion implantation, for this purpose can be considered a promising solution. We study the microstructure, phase and elemental compositions, wetting forces, and electrical properties of steel with implanted ions of titanium, aluminum, and molybdenum. The results obtained by means of XRD, XPS, optical microscopy, and laboratory experiments show sig- nificant differences between the treated and untreated specimens. The modification of metal by ion implantation causes changes in the wettability and electrical characteristics and indicates the prospects of this technology for mechanical engineering, chemical, food, pharmaceutical industries, for the construction of structures and vehicles, including their work under severe atmospheric conditions.
