Chapter
A range of additives of different nature and their binary mixtures have been investigated in regard to their influence on the metal degradation processes. It was shown the applicability of the thermodynamic state and transitions diagrams for analysis of electrochemical processes and interactions during the development of metal protection methods ba...
Article
The regularities of joint action of the additives characterized by different inhibition mechanisms for the protection of mild steel in aqueous saline media are investigated. We study, in total, 14 inhibiting mixtures with different concentration ratio. The accumulated results on the protective efficiency and produced morphological and structural mo...
Chapter
The processes of formation of phase protective layers in the presence of numerous individual inhibitors and their mixtures have been investigated. The results of characterization of the protective films for determining the influence of the concentration ratio of the mixture components and the deposition conditions on the distribution of elemental c...
Article
The protective ability of corrosion inhibitors for steel in aqueous saline solutions is ensured for the metal potentials and pH values transferring, according to the Pourbaix diagram, the Fe–H2O system into a thermodynamically stable state of hydrated oxides of Fe (III). Under these conditions, the binary mixtures of the inhibitors of oxidation and...
Conference Paper
Statistical analysis and mathematical modeling have been employed to investigate the energy generation and consumption processes in heterogeneous power generation environment with different renewable energy sources. The obtained model for predicting the power generation-consumption imbalance has been presented and its applicability for optimization...

Regularities of the phase protective layer formation in multicomponent systems involving inhibitors with different mechanism of protective action have been investigated. It was shown that optimization of the composition of the inhibition mixture allows to obtain higher protective efficiency owing to improved microstructure of the phase layer. It wa...
Conference Paper
A range of methods for obtaining poly(diphenylamine)-AgNP nanocomposites have been studied, and resulting hybrid materials have been characterized using SEM, TEM, AFM as well as IR spectroscopy methods. It was found that the one-step preparation method has a significant advantage over the two-step one in terms of stability of the results. The adapt...
Article
We study the conditions of appearance of synergistic effects in inhibiting mixtures aimed at the protection of steel against corrosion in neutral aqueous-salt and acid media. It is shown that the high anticorrosion efficiency in neutral media is attained by the application of inhibitors with different mechanisms of action guaranteeing the efficient...
Conference Paper
Full-text available
A promising research area is the development of methods for obtaining hybrid materials and nanocomposites which are based on the introduction of the nanoscale objects into the polymeric matrix. Of particular interest are thin films of conducting polymers with incorporated palladium or silver nanoparticles, as well as bimetallic core–shell objects....
Chapter
The coating deposition method based on oxidizing polymerization of aniline derivatives directly on substrate in the presence of Fe3+ ions under galvanostatic conditions is demonstrated. It was shown that infusion of Fe2(SO4)3 and KI to the system leads to greatly accelerated polymeric film formation process due to direct participation of added Fe3+...
Article
Full-text available
Combined inhibitive and surfactant compositions with synergetic action of individual components have been developed and studied. Application of these compositions for corrosion protection of metals in aqueous saline media and for processes of electro-spark and mechanical machining of their surface was discussed. The experimental study and mathemati...
Article
We study the principal kinetic regularities of the formation of protective metalloorganic films in acid media in the presence of complex-forming corrosion inhibitors and propose an equivalent scheme of the metal/electrolyte interface taking into account the polarization resistance of diffusion of the phase layer and intended for the analysis of the...
Article
The new data and the data available in the literature on the use of the processes of complex formation for protection of metals against corrosion are analyzed. Using the example of cysteine, we show the applicability of the conception according to which the protective effect of some organic inhibitors is due to the formation of partially soluble co...
Article
Triphenylphosphine oxide (TPPO) as an inhibitor of acid corrosion of iron was analyzed. The 3kp08 steel were immersed in solutions of 0.5 M H 2SO4at 18°C with and without TPPO dissolved to saturation. Triphenylphosphine oxide was added to H2SO4 in a great excess to 0.5 g/l so the corrosive solutions were saturated with TPPO. The specimens were expo...
Article
The anodic dissolution rate of the iron-family metals is analyzed depending on the anionic composition of aqueous electrolyte solutions. Investigation of the process in a broad range of potential values (including the limiting current range) in solutions with the controlled content of cations and anions enables us to discover the diffusion limitati...
Article
Based on the hypothesis of the reversibility of an iron electrode, one can relatively easily explain the experimentally obtained Tafel slopes without multistage complex schemes involving hypothetic intermediate iron hydroxo compounds. On the other hand, the coincidence of the experimental slope with the slope following from the relation derived may...
Article
We show that a limiting current of diffusion nature is observed on the anodic polarization curves of iron and its analogs in relatively dilute acid solutions. The values of this current do not depend directly on the pH of the solution, but are related to the anion concentration. The last feature formed the basis of the hypothesis that the limiting...
