Abstract

FIELD: voltmetric studies for determination of potentio- and galvanostatic and dynamic curves, particular for determination of corrosion rate, selection of additives in electroplating processes, study of surfactants effect on cathode and anode processes. SUBSTANCE: device for electrochemical measurements has three-electrode system in which working electrode is used in form of a part of tested specimen in which measuring cell is installed, which accommodates comparison electrode and auxiliary electrode. Measuring cell is filled with liquid electrolyte and provides for contact of working electrode with electrolyte and allocation of always same area due to use of pressing unit. EFFECT: reduced time for preparation operations, high accuracy of measurements and their reproducibility.

Изобретение относится к электротехническим измерениям и может быть использовано при вольтамперометрических исследованиях для снятия потенцио- и гальваностатических и динамических кривых, в частности для определения скорости коррозии, подбора добавок в гальванических процессах, изучения влияния поверхностно-активных веществ на катодные и анодные процессы и т.д. Устройство содержит трехэлеткродную систему, в которой в качестве рабочего электрода использован участок исследуемого образца, на котором установлена измерительная ячейка с расположенными в ней элеткродом сравнения и вспомогательным электродом, заполненная жидким электролитом и обеспечивающая контакт рабочего элеткрода с электролитом и выделение всегда одинаковой площади за счет использования узла прижима. Использование устройства позволяет снизить время подготовительных операций при выполнении серии параллельных измерений, сохраняя при этом постоянство площади поверхности рабочего электрода и следовательно обеспечивая точность и воспроизводимость измерений. Кроме того, устройство дает возможность при небольшой площади исследуемого образца обеспечить выделение максимального числа близко расположенных друг к другу участков для проведения серии паралллельных измерений на образцах не только с плоской, но и выпуклой, вогнутой, выпукло-вогнутой, цилиндрической и т.д. поверхностью.The invention relates to electrical measurements and can be used for voltammetric studies to take potential and galvanostatic and dynamic curves, in particular for determining the corrosion rate, selection of additives in galvanic processes, studying the effect of surface-active substances on cathodic and anodic processes, etc. . The device contains a three-electrode system, in which a portion of the test sample is used as a working electrode, on which a measuring cell is installed with a reference electrode and an auxiliary electrode located in it, filled with liquid electrolyte and providing contact between the working electrode and the electrolyte and always identifying the same area by using the unit clip. Using the device allows to reduce the time of preparatory operations when performing a series of parallel measurements, while maintaining a constant surface area of the working electrode and therefore ensuring the accuracy and reproducibility of measurements. In addition, the device makes it possible for a small area of the test sample to ensure the allocation of the maximum number of closely spaced sections for conducting a series of parallel measurements on samples not only flat, but also convex, concave, convex-concave, cylindrical, etc. surface.
