Abstract

Настоящее изобретение относится к способу контроля качества поверхности отложений, образованных на поверхности электрода при электролитическом осаждении металлов. Согласно данному изобретению катод (1), используемый в электролитическом процессе, освещают с помощью, по меньшей мере, одного светового источника (3), установленного под углом к плоской поверхности (12), образующей поверхность катода, и изображение освещенной поверхности (12) получают с помощью, по меньшей мере, одного съемочного аппарата (8); указанное изображение затем передают в устройство для обработки и анализа изображения (9) и на основе полученного изображения определяют возможные неоднородности на контролируемой поверхности для того, чтобы классифицировать полученный на катоде осадок (11) для проведения дальнейшей стадии обработки.Международная заявка была опубликована вместе с отчетом о международном поиске.
