Obraztsov V. Influence of the electrode's nature on the inhibiting effect of the surface active organic substances

The subject of investigation: charge transfer occuring on different electrodes at fixed coverage of their surface with organic adsorbate. Purpose of investigation: generalization of electrode processes regularities of adsorptional polarization nature on the base of systematic studies and solution of creation problems of new generation of corrosion inhibitors as well as of chemically modified electrodes. Methods of investigation: voltammetry, impedance spectroscopy, coulostatic method, atomic-absorbtional spectroscopy, radiostructural analysis, optical emissional spectroscopy. For the first time the systematic kinetic data for ion- and electron transfer reactions which occur at fixed coverage of different electrodeswith the adsorbate were obtained; dependence of the inhibiting effect of organic substances on electrode's nature was also revealed. The comprehensive development of coulostatic measurements was first reached out, including correlation for the constant phase element, design of optional types of the hardware, creation of new types of chemically modified electrodes, as well as elaboration of the methodology and the software for corrosion, analytical and fundamental investigations. The established regularities in adsorption and in inhibiting effect of the polyelectrolytes were used in creation of new series of high-performance inhibitors of the acidic corrosion of steel and chemically modified electrodes. The results of the dissertation can be used at development of new technologies of metals electrodeposition and corrosion inhibitors following with their application in machine-building, heat-and-power engineering, oil- and gas-producing industry.
