Abstract

The establishments of rust converters or rust transformers have always been under scrutiny. Although the main mechanism of these transformers has not yet been confirmed, but these rust convertor react with iron oxides and produced new compounds which caused to passivate the surfaces. These transformers are mostly composed of phosphoric acid and tannic acid. We present the study of some rust converters or transformers which were painted on the mild steel samples. The anti corrosive properties of three different compositions of rust converters were investigated. The performance of samples was monitored with the Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy, and Electrochemical Impedance Spectroscopy. This research showed that the efficient chemical formulation of phosphoric and tannic acid plays much important role in the rust conversion properties. It gives more polarization impedance and more protective layer as compared to the other compositions.
