Vappro Corrosion Control Australia is pleased to present a comparative study, published by Dr. Nelson Cheng, from our partner, Magna International Pte Ltd, on removing rust and corrosion using Molecular Reaction Surface Technology (MRST), against other conventional forms of corrosion treatment on carbon steel, using electrochemical impedance spectroscopy (EIS). The first aim was to understand what advantages MRST presented over other current forms of corrosion treatment. The second aim was to understand the effect of each corrosion treatment method on the metal surface and to discover if any of these methods were able to passivate the surface of the metal to prevent it from future corrosion. In this research, a I/E Tafel plot is utilised to obtain the transfer current of the electrochemical cell to determine the corrosion rate of the carbon steel specimens. The corrosion rates of the carbon steel specimens serve as a comparison to the effectiveness of the various corrosion treatment methods and to discover if any surface passivation had occurred on the metal surface after treatment. The present research is able to discuss the similarities between MRST and other commercial and common methods of corrosion treatment and highlights some key findings that should be further studied in future research.
