“…A plot of real part of impedance ( ) and imaginary part of impedance ( ) was made, and from this, the charge transfer resistance ( ct ), double layer capacitance ( dl ), and inhibition efficiency were calculated using ZView software. The inhibitor efficiency was obtained from the electrochemical parameters as below [9][10][11]…”

No discussion of the use of inhibitors in acid solution is complete without mentioning the phenomenon of synergism. Synergism also operates in corrosion protection where an enhanced inhibition may be related to interaction between inhibitor compounds. This effect has been observed since the earlier days of inhibitor technology and continues to be a potent tool in the development of acid inhibitors for specialized uses. Hence, in this paper, the corrosion inhibition behavior of mild steel (MS) in 1 M hydrochloric acid in the presence of 4-hydroxy coumarin (4HC) and potassium iodide (KI) has been investigated using the mass loss method and electrochemical techniques. The inhibitive performance of 4HC is considerably enhanced by the addition of KI. The addition of KI to different concentrations of 4HC has intensified its efficiency through considerable reduction in the mass loss, corrosion current density , double layer capacitance , and increase in charge transfer resistance . The calculated synergism parameter “” is greater than unity, thereby proving the fact that the improvement in inhibition efficiency of 4HC, generated by the addition of KI, is due to synergism.

In this study, the electro-chemical behavior of Udimet700 alloys is studied in acidic media at 25°C. It deals with the corrosion inhibition process of nickel–based (Udimet700) alloy in 1M–HCl solution by some organic derivatives. The methods used include electro–chemical frequency modulation technique, electro–chemical impedance spectroscopy, and potentio–dynamic polarization. The derivatives are considered as mixed–type inhibitor depending on potentio–dynamic polarization analysis. Scanning electron microscope examination is executed to study the morphology of Udimet700 surface after immersion in a solution in the case of presence and absence of derivatives. The results of this research reveal that the inhibitors are absorbed by Udimet700 alloy surface and they insulate it from the acidic medium. The compound (C16H17) among the tested organic derivatives plays the best role as an inhibitor of the alloy in 1M–HCl.
