A study on the filming kinetics of corrosion inhibitors in Fe/Na2SO4 system using EQCM
Source abstract
Abstract
Abstract Electrochemical Quartz Crystal Microbalance (EQCM), a new electrochemical technique developed in recent years, has been employed to study the filming kinetics of corrosion inhibitors in Fe/Na2SO4 neutral system. An equation was deduced to calculate the real mass change of the electrode surface during the filming and some experimental isothermal curves of filming kinetics of corrosion inhibitors were found. It is found that the film growth on iron in Na2SO4 solution follows the parabolic law in the presence of the oxidizing inhibitor NaNO2, similar to oxidation kinetics of some metals at high temperature, or the linear law in the presence of the precipitating inhibitor Na2SiO3.
