Glutamic Acid Derivatives

The Self-Assembled (SA) films of glutamic acid derivatives were prepared on the iron surface. Electrochemical impedance spectroscopy (EIS) and polarization techniques were used to investigate the protection abilities of these films against iron corrosion in 0.1 M H2SO4 solution. The results of EIS and polarization curves indicated that films of the glutamic acid derivatives were able to protect iron from corrosion effectively.

This work deals with localized electrochemical impedance spectroscopy (LEIS) which is an improved technique of the commonly used electrochemical impedance spectroscopy (EIS). Thanks to modern structural solutions, the LEIS technique ensures local impedance measurement. Therefore, it is used in the research into point corrosion, such as the pitting corrosion, and in the research into protective coatings or into alloys including alloy steels. This review paper presents the basic theory and the usability of the LEIS based on the literature on the newest research in the field of corrosion.
