Metal 2015. Conference proceedings.
Samples in the form of an assembly of two tightly pressed Zr (0,3 mm), Ti (0,25 mm) and Ni (0,1 mm) foils were irradiated with 15 pulses high deuterium plasma (up to 10 keV) on the "Plasma focus "(PF-4, FIAN) [1, 2] for the creation of shock waves and deuterium ion implantation. Options PF-4 and deuterium plasma exposure conditions and posleradiatsionnyh studies described in [1, 2]. It performs measurements of the neutron yield from all assemblies foils. Studies of foil on both sides by recording recoil nuclei (ERDA) showed that deuterium ions under the influence of shock waves knocked out of the first foil and penetrate into the second foil of the same composition as initially present in the sample hydrogen redistributed. The measured depth profiles of all distributions and integral concentration of deuterium and hydrogen, both sides of each of the foils are presented. The model describing the observed effects in the first knockout implanted deuterium foil and redistribution of impurities under discussion. SEM studies of changes made and the elemental composition of the surface, the results are discussed.
There are many different methods of deposition of films on the dielectric material and the metal surface , such as magnetron sputtering and thermal materials , methods, and electrolytic chemical deposition , etc. However , after the film deposition to improve their adhesion to the substrate is necessary to apply chemical and thermal treatment, which often leads to uncontrolled changes in the physical properties of the films . Thus, the search for alternative methods of deposition of films that do not require additional costs for thermal and galvanic chemical treatment remains valid . This paper proposes a method of applying metallic films on glass substrates using pulsed plasma obtained by installing a Plasma Focus ; describe a scheme of the experiment and the results of investigations of the obtained films.
The work carried out research on the use of pulsed high-temperature plasma for the preparation of compounds of immiscible materials. The technique of irradiation on materials installation type Plasma Focus.
The paper investigated the redistribution of hydrogen and deuterium in the assemblies of metallic foils Ta | CD2 | Ta, Ta | Ta | CD2 | Ta | Ta and Nb | CD2 | Nb, irradiated pulses of high-argon plasma at a plasma focus. Irradiated samples foils were investigated by detection of recoil nuclei of hydrogen and deuterium (ERDA). It found ultradeep penetration in the target light gas impurities (hydrogen and deuterium). It is assumed that this phenomenon is due to the influence of shock waves generated by a plasma pulse, and acceleration of diffusion processes.
