Abstract

Изобретение относитс  к электрохимическим исследовани м коррозионных характеристик металлов при высоких температурах . Целью изобретени   вл етс  упрощение способа путем использовани  в качестве вспомогательного электрода и электрода сравнени  покрыти  из металла образца , нанесенного на внутреннюю поверхность автоклава. Способ заключаетс  в том, что на поверхность автоклава нанос т покрытие из металла образца, которое может быть выполнено в виде оболочки, наружна  поверхность которой повтор ет внутреннюю поверхность автоклава, размещают в автоклаве образец, пол ризуют его и определ ют его катодные и анодные характеристики , в качестве которых используют смещение анодных и катодных потенциалов образца относительно покрыти . Стро т кривые этих смещений, по которым суд т о скорости коррозии. 1 3. п. ф-лы, 2 ил. i (ЛThis invention relates to electrochemical studies of the corrosion characteristics of metals at high temperatures. The aim of the invention is to simplify the process by using as a secondary electrode and reference electrode a metal coating of a sample deposited on the inner surface of an autoclave. The method consists in coating the surface of the autoclave with a metal sample, which can be made in the form of a shell, the outer surface of which repeats the inner surface of the autoclave, place the sample in the autoclave, polarize it and determine its cathodic and anode characteristics, which is the displacement of the anodic and cathodic potentials of the sample relative to the coating. The curves of these displacements are constructed, according to which the corrosion rate is judged. 1 3. p. F-ly, 2 ill. i (L
