The following scientific and technological basis have been developed

• methods of surface modification of metal materials using electron-beam, plasma, microplasma, laser and combined effects
• methods of obtaining permanent joints using electron-beam effect

The concept for the development of physical and technological processes of electron-beam treatment has been developed. It is based on physical and mathematical models and experimental data collection on the influence of electron-beam effect parameters on the temperature field formation in the material by a variation of electron beam parameters (power density, exposure time and geometric characteristics of the flow)

Methods to manage formation processes of given structural and phase states and properties of surface and transition layers provide the following

• giving the parts from steel and titanium, aluminum, copper and other alloys (including those with preliminary deposited  coatings) the properties  that are impossible to reach using other methods of volume and surface hardening
• obtaining high-strength permanent joints of uniform (metal-metal) and dissimilar (ceramics – metal) materials; effect in a deep alloying mode which provides by varying the power density, displacement rate and the plane position of the focal spot of a bunch relative to the surface of manufacturing mechanical engineering parts with a decrease in the material consumption of units up to 50%

The formation by ion-plasma thermochemical treatment methods with minimal power consumption, high  serial stability and reproducibility of treatment results on products from steels, cast iron and titanium alloys of uniform hardened layers of a given composition, depth and hardness is reached due to applying ripple voltage with a fixed current pulse duration, presence of heat-protection system of the chamber as a working environment of N2+H2+Ar gas mixture (with the addition of methane or propane-butane, if necessary), fully automated computer control of the equipment  at all stages of the process
