Adhesion, physicomechanical properties, and also kinetics of water absorption of priming coatings on basis the E-41 epoxy resin modified by liquid Thiokol 1 and by Laproxide AF, and also their phase structure are investigated. As hardeners of primer compositions organic silicon ammine ASOT-2 and low-molecular polyamide PO-200 has been used. It is shown that use of the reactive modifier Laproxide AF and hardener ASOT-2 in the epoxy and thiokol film-formers allows to receive priming coating with uniform finely divided phase structure with low porosity and high water resistance.

The present work is devoted to research the influence of micro-structural evolution of the compound zone (iron (carbo)nitrides zone) upon development of hardness profiles in diffusion zone. A different phase structure of iron (carbo)nitrides zone on steel as compared to iron, further changing with the process, may result in upsetting the quasi-equilibrium of nitrogen concentration in the iron (carbo)nitrides zone/diffusion zone interface and may as a result have impact on the kinetics of this layer’s growth. Aimed at solving this problem there was a research carried out to evaluate influence of (carbo)nitrides zone, with intentionally created diametrically different phase composition, on hardness profiles in the diffusion zone. Based on the research conducted, it was shown that the evolution of phase structure of the compound zone contributes significantly, regardless of nitrogen potential and temperature, to the formation of the diffusion zone and in particular to its effective thickness. It makes this complex picture of nitrided case development on steel even more intricated.

With the goal to find hydride electrodes, the phase structure and electrochemical characteristics of the as-cast and ball-milled La2Mg17 alloy with Ni additions were investigated. The addition of Ni was found to be an important factor for the earlier transformation to an amorphous alloy. When the addition of Ni reached 100 wt%, the ball-milled La2Mg17 alloy transformed into a homogeneous phase with high discharge capacity of 1060 mAh/g(La2Mg17) [530 mAh/g(La2Mg17+100 wt% Ni)]. The exchange current density and the kinetics of the amorphous alloy were also found experimentally noticeably higher than those of corresponding crystal alloy.
