Влияние анионов на коррозионно-электрохимическое поведение стали Ст3 в сульфатных средах. Сообщение 2. Поляризационные измерения

Abstract

Потенциодинамическим методом исследовано коррозионно- электрохимическое поведение стали Ст3 в сульфатсодержащих растворах при 25 °С, C(SO4 2–) = 0,1 моль/л и pH 0,08; 0,66; 1,66; 4; 6,6; 8,5 и 11,5. Сопоставление поляризационных кривых с диаграммой электрохимического равновесия стали позволило разобраться в особенностях коррозионного состояния стали в исследуемом диапазоне pH и потенциалов поляризации. Corrosion-electrochemical behavior of steel St3 in sulfate-containing solutions has been investigated at 25°С, C(SO4 2–) = 0.1 mol/L, and pH 0.08; 0.66; 1.66; 4; 6.6; 8.5 and 11.5. Comparison of the polarization curves with the diagram of electrochemical equilibrium has offered a clearer understanding of the corrosion state peculiarities of steel within the investigated range of pH and potential polarization.
