В данной статье представлен обзор данных исследований относительно новых процессов электрохимической обработки, классифицируемых под общим названием процесса электролитно-плазменной термической обработки поверхности из различных исследовательских работ. Обзор сделан для расширения исследовательской работы по этому новому процессу промышленного зрения и охвата. Особое внимание уделено перспективам его использования для модификации и покрытия поверхностей. Были обсуждены различные виды электролитно-плазменной обработки, чтобы проиллюстрировать возможности процесса улучшения свойств поверхности различных металлов. По сравнению с существующими процессами термообработки обработка занимает меньше времени, является экономичной, экологически чистой и динамичной. Его динамические возможности включают цементирование, азотирование, покрытие, очистку, полировку и т.д. для упрочнения в одной экспериментальной установке путем внесения небольших изменений позволяет выполнять операции. Показаны режимы обработки и состав электролитов, особенности строения обрабатываемых слоев, их микротвердость и шероховатость поверхности, трибологические и антикоррозионные, т.е. физико-механические свойства в различных средах. В целом определены режимы обработки, позволяющие значительно повысить противоизносную и коррозионную стойкость сталей. Сделан вывод о перспективах электролитно-плазменной обработки, отмечены преимущества и ограничения этого метода, в том числе предполагаемые направления дальнейших исследований.
