Рассмотрено современное состояние «формальной теории» ингибирования коррозии. Показано, что ингибиторная защита может происходить за счет экранирования поверхности металла и роста энергии активации коррозионного процесса. Общий коэффициент торможения коррозии определяется произведением парциальных коэффициентов торможения по блокировочному и активационному механизмам. Установлено, что для систем, спектры электрохимического импеданса которых описываются эквивалентной схемой Мансфельда, возможна количественная оценка парциальных коэффициентов торможения по обоим механизмам. Анализируются формулы, для оценки взаимного влияния компонент бинарных смесей ингибиторов (аддитивность, синергизм, антагонизм) по данным о степенях или коэффициентах защиты металла, а также временах предотвращения коррозии, для смесей и ее составляющих. Смещение не взаимодействующих друг с другом камерных ингибиторов сопровождается ростом эффективности защиты относительно компонент.

The current state of the “formal theory” of corrosion inhibition is considered. It is shown that inhibitor protection can be achieved by shielding the metal surface and increasing the activation energy of the corrosion process. The overall corrosion inhibition coefficient is determined by the product of the partial coefficients of corrosion inhibition by the blocking and activation mechanisms. It is demonstrated that the quantitative estimation of the partial inhibition coefficients for both mechanisms is possible for systems whose electrochemical impedance spectra are described by the Mansfeld equivalent circuit. The formulas are analyzed to evaluate the mutual interaction of the components of binary inhibitor mixtures (additivity, synergism, antagonism) using data on the degrees or coefficients of metal protection for the mixtures and their components, as well as corrosion protection times. Mixing chamber inhibitors that do not interact with each other is accompanied by an increase in protection efficiency compared to the individual components.
