The Study of Aerosol Corrosion Mechanism at the Tinplate-Liquid Interface

The traditional method to evaluate corrosion in aerosol can is the optical examination of the opened aerosol metal as a function of the storage environment. In this paper EIS (Electrochemical Impedance Spectroscopy) and polarization techniques are shown to successfully evaluate the internal corrosion reaction mechanism at the liquid-metal interface in aerosol can environments. The interface corrosion reaction rate was also estimated successfully through the application of linear polarization. The technology provides powerful monitoring and prediction tools for real-time liquid-tinplate corrosion mechanism study.
