Thus the basic accent became on studying of influence of ionic-plasma processing (IPP) which includes sedimentation of ionic-plasma coatings and ionic implantation, on mechanical properties of samples from pieces zirconium tubes an alloy of Ukrainian manufacture Zr+1%Nb. On these samples were deposited single-layered (Ti, TiN), multilayered with layers which alternate (Ti+TiN)x, (Zr+ZrN)x, and multicomponent composite alloyed nanostructure TiАlN, TiAlSiN, TiA-lYNn coatings. Some samples there were added alloying additives Zr+, Mo+, N2+ and О2+. After IPP samples were put on trial on a stretching on installations «ІNSTRON-5581» and the vacuum tearing device 1246Р-2/2300. By results of tests were defined durability border sigma (b), conditional border of fluidity sigma (0,2), the general delta (5) and uniform delta (p) relative lengthening, an exponent of deformation hardening n, and also the elasticity module. It is shown, that sedimentation of the protec-tive is ionic-plasma coatings leads to increase in border of durability sigma (b) on tearing from 12 to 21 % at 350oC, and the conditional border of fluidity sigma (0,2) remains thus practically invariable. After an ionic irradiation has considerably increased (to 16 %) conditional border of fluidity sigma (0,2). It is shown, that investigated coatings ~5 microns have in the thickness high hardness (to 45 GPa), and after IPP the increase in hardness and the module of elasticity of the processed samples is noted. System of Ti-Al-N coatings widely use for protection of workpieces which are exploit in extreme con-ditions, such as the high temperatures in air atmosphere. According to literary data, in such conditions their surface takes cover a thin layer of oxide which protects deep layers of a film and constrains oxi-dation. Hardness of coatings Ti (1-x) AlxN reaches the greatest values (~40 GPa) when h=0,5-0,6, and the firm solution with structure NaCl is formed. Coatings deposition from the filtered plasma allows improving their quality considerably. Additional possibilities are given by giving on a substrate of high-voltage pulse potential which gives the chance to receive a coating with high thickness at the expense of improvement of adhesion and reduction of level of mechanical pressure. It is known, that introduction yttrium in structure of nitride coatings leads to increase in resistance to oxidation and improvement mechanical that tribological properties. The purpose of this work is also reception and research of structure and properties of coatings Ti (0,5) Al (0,5) N, alloyed by small quantity Y (to 1 at. %), besieged by means of a vacuum-arc source of the filtered plasma and a substrate biased of high-voltage impulses of potential by amplitude to 2.5 kV. This research is logic continuation of work which has been spent by us at the previous stage in the first half of the year 2012. This half-year we have concentrated the attention to studying of influence of size of amplitude of high-voltage pulse bias substrate potential on structure and properties multicomponent nitride coatings. It is cited also data about development of thermoelastic peak at interaction of a plasma stream with a substrate and conditions of drop dispersion of some metals are found.
