The article considers a method for obtaining deuterium storage on titanium samples. The depth of penetration of deuterium ions into the outer surface of porous titanium is calculated by increasing the resistance of the samples. Higher resistance of the samples is shown to be caused by the creation of a dielectric layer of titanium deuteride on the surface. It was proven that the depth of penetration of deuterium ions into the surfaces of the samples is significantly greater than the classical concept about the doping process explains. The design of an ion doping unit contains a vacuum working chamber with a working table for placing samples. The ion beam comes from an ion source in crossed electric and magnetic fields of the Penning type. The working gas of the ion source is deuterium. The ion source gas is supplied through a special fitting in the design of the ion source, connected to the deuterium cylinder through a special leak. The working chamber is pumped out by a high-vacuum unit, to which a pre-vacuum pump is connected at the outlet. The ion implantation unit is electrically powered from three power sources. A power supply with a voltage of up to 5 [kV] and a current of up to 100 [mA] feeds the gas discharge of the source. The 10 [kV] power supply gives a negative potential to the target, and deuterium ions coming out of the hole in the cathode of the ion source are accelerated towards the desktop with the power supply up to 40 [kV] and up to 10 [ma].

The article considers the advantages of the ion implantation method compared to the existing methods of vacuum sputtering. It is shown that surface properties can vary considerably and the surface treatment can cause the increase of the sample material surface area. The article also provides the evidence proving that after ion implantation the surface enhances its catalytic activity and changes its mechanic properties. It presents the ion implantation unit used to implement this method along with its operating principle. The authors describe a technological coating process for work surfaces of various intended uses. The article provides the results of application of hardening coatings onto the tool for wood products processing, onto a perishable hard-carbide tool with mechanical mounting, onto a high-speed cutting tool and on face mills with hard-alloy soldering in metalwork, catalytic coatings in car industry and heat and power engineering. The results of the tests performed on the products treated with ion implantation demonstrated that the installation of ion (corpuscular) implantation enables getting catalytic surfaces, enhancing strength, wear-, heat-and corrosion resistance of equipment.

The advantages of ion implantation method compared to existing methods of vacuum deposition. It was shown that the surface properties may vary within a wide range. The specific surface of the sample material may increase after the surface treatment. As a result of implantation the surface enhances catalytic activity and modifies the mechanical properties. There is a presentation an ion implanter for the implementation of the method and how it works. A process for applying the catalytic coatings working surfaces for various purposes is disclosed. The results of X-ray diffraction analysis of samples are introduced into the surface by alloying the catalyst corpuscular ions. The research on prototypes of various shapes. As a result, comparing them with samples.
