Показано, что заисключением начального периода практически в течение всего процесса импеданс электролитической ячейки определяется импедансом контакта электро лита и оксида титана на дне нанопористого и нанотрубчатого слоев. Обнаружено, что электрическое сопротивление области пространственного заряда вслое оксида титана выше, чем сопротивление переноса заряда на границе раздела электролит/TiOx. Это свидетельствует о том, что скорость роста пористого и нанотрубчатого слоев, полученных травлением в органо− неорганическом электролите, ограничена переносом ионов титана и кислорода через слой оксида, а не диффузией ионов в электролите.</p></abstract><trans-abstract xml:lang="en"><p>Nanoporous and nanotubular titanium oxide layers were fabricated by electrochemical etching in a mixed organic–inorganic electrolyte. The process of layers formation was investigated in−situ using the electrochemical impedance spectroscopy method. The experimental data show that, except for an initial stage of electrolytic etching, the impedance of a porous titanium oxide layer during almost the entire process is determined by the impedance of a small contact area of electrolyte/titanium oxide at the bottom of the nanoporous and nanotubular layers. The observed higher resistances of space charge region in the titanium oxide layer in comparison with the resistance of charge transfer at the electrolyte/TiOx boundary testify that the growth rate of porous and nanotubular layers is limited by the diffusion of titanium and oxygen ions through the oxide layer, and not by the diffusion of ions in the electrolyte.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оксид титана</kwd><kwd>нанопористый</kwd><kwd>нанотрубчатый</kwd><kwd>импеданс</kwd><kwd>электролит</kwd><kwd>травление</kwd><kwd>проводимость</kwd><kwd>электронная микроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>titanium oxide</kwd><kwd>nanoporous</kwd><kwd>nanotubular</kwd><kwd>impedance</kwd><kwd>electrolyte</kwd><kwd>etching</kwd><kwd>conductivity</kwd><kwd>electron microscopy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mor, G.
