В статье рассмотрены вопросы измерения потенциала коррозии и основных закономерностей его установления для гетерогенных корродирующих сплавов повышенной коррозионной стойкости, с целью возможности применения метода потенциометрии при определении стойкости против межкристаллитной коррозии. Для сохранения критерия достоверности метода потенциометрии относительно метода АМУ по ГОСТ 6032-2017 учтена зависимость устойчивости нержавеющих сталей против межкристаллитной коррозии и величина их электрохимического потенциала от свойств окружающей среды за счет использования в качестве испытательного электролита раствора серной кислоты и сульфата меди. С этой же целью изготовление образцов из заготовок, их подготовка, провоцирующий нагрев и выдержка в кипящем растворе проводились по методу АМУ в соответствии с требованиями ГОСТ 6032-2017.</p></abstract><trans-abstract xml:lang="en"><p>The article discusses the measurement of the total electrode potential and the basic patterns of its establishment for heterogeneous corroding alloys with increased corrosion resistance, with the aim of applying the potentiometric method to determine resistance against intergranular corrosion. In order to maintain the reliability criterion of the AMU method according to GOST 6032-2017 the dependence of the resistance of stainless steels to intergranular corrosion and the value of their electrochemical potential on the properties of the environment has been taken into account by using a solution of sulfuric acid and cooper sulfate as the test electrolyte. For the same purpose, the preparation of samples from blanks, their preparation, provoking solution were carried out using the AMU method in accordance with the requirements of GOST 6032-2017.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>межкристаллитная коррозия</kwd><kwd>металлические сплавы</kwd><kwd>потенциометрия</kwd><kwd>поляризация</kwd><kwd>потенциал коррозии</kwd><kwd>гальванические пары</kwd><kwd>пассивный слой</kwd><kwd>репассивация</kwd><kwd>динамика потенциала</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intergranular corrosion</kwd><kwd>metal alloys</kwd><kwd>potentiometry</kwd><kwd>polarization</kwd><kwd>corrosion potential</kwd><kwd>galvanic couples</kwd><kwd>passive layer</kwd><kwd>repassivation</kwd><kwd>potential dynamics</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Благодарим за сотрудничество и рекомендации по выполнению работы профессора кафедры металлургии стали, новых производственных технологий и защиты металлов НИТУ МИСиС Ракоча А.Г. и главного специалиста по коррозионной защите ООО «Центр Сертификации» Монахову Е.П.</funding-statement><funding-statement xml:lang="en">We thank Professor A.G.
