ИЗУЧЕНИЕ КОРРОЗИОННОГО ПОВЕДЕНИЯ Co-W ПОКРЫТИЯ В РАЗЛИЧНЫХ СРЕДАХ
Аннотация
Методами электрохимического импеданса и поляризационных измерений изучено коррозионное поведение Со-W покрытий, полученных из цитратного электролита (с содержанием W в покрытии ~24 ат. %) в следующих коррозионных средах: 0,6 М хлориде натрия, 0,1 М сульфате натрия (Na2SO4), 1М соляной кислоте (HCl) и 0,5М серной кислоте (H2SO4). В качестве сравнения взята сталь JIS-SK5, выступающая в качестве подложки при осаждении. Показано, что токи коррозии Co-W покрытий в трех коррозионных средах (хлориде натрия, соляной кислоте и сульфате натрия) близки, и составляют 20±3 мкА/см2. В серной кислоте значения токов коррозии ниже и составляют ~10 мкА/см2. При выдержке в кислых средах коррозионный потенциал Co-W покрытий сдвигается в анодную область, достигая значений -0,26 В, а в нейтральных средах (хлоридной и сульфатной) достигает существенно более низких значений -0,72 В. Продемонстрированы высокая пассивирующая способность Co-W покрытия в используемых кислотах, где токи коррозии более чем в 100 (в случае серной кислоты) и в 17 (в случае соляной кислоты) раз меньше, чем у подложки из стали SK-5. Максимальное поляризационное сопротивление Со-W покрытий наблюдается в средах хлорида натрия и серной кислоте и принимает максимальное значение ~36000 Ом·см2, а минимальное значение данное покрытие показывает с солянокислой среде ~ 3500 Ом·см2.
