Разработаны модель, алгоритм и проведен расчет тепловой мощности, выделенной в единице объема барьерного слоя оксида алюминия с различной пористостью пленки. Установлено, что при низкой пористости исследуемых структур тепловыделение в области границы дна поры значительно превышает тепловыделение в других областях пористого оксида, что приводит к локальному разогреву этих мест и появлению микроплазменных образований во время процесса анодирования. Приведены рекомендации по увеличению эффективности теплоотвода, позволяющие улучшить равномерность формируемых пористых пленок.</p></abstract><trans-abstract xml:lang="en"><p>Heat-segregation calculations inside porous alumina barrier layer have been performed. It is shown that Joule heat on pore bottom surface is four orders of magnitude greater than in other porous oxide areas. This effect leads to local heating of this areas and microplasma formations during anodizing process. The recommendations about the heat dissipation efficiency increasing in order to improve the uniformity of the structures have been advised.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрохимическое анодирование</kwd><kwd>алюминий</kwd><kwd>барьерный слой</kwd><kwd>оксид алюминия</kwd><kwd>джоулево тепло</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">Lazarouk S., Katsouba S., Leshok A., et. al. // Microelectronic Engineering. 2000.
