Special Issue Information

Dear Colleagues,

Corrosion is the process of the deterioration of metals and alloys due to the reaction with the surrounding environment, particularly in the presence of oxygen and moisture. This phenomenon can weaken the structural integrity of the material, leading to functional failure.

Corrosion inhibition is the technique of preventing or reducing the corrosion rate of metals and alloys by using chemical compounds. This is done by adding inhibitors to the surrounding environment or coating the surface with inhibitor substances. Inhibitors work by forming a protective layer on the metal surface, hindering the reaction between the metal and corrosive agents. The effectiveness of corrosion inhibition depends on the type of material, the environment, and the inhibitor selected. Proper selection of inhibitors can save significant costs and resources, and ultimately help to prolong the lifespan of the equipment. Corrosion inhibitors have widespread applications in suppressing or at least mitigating the corrosion process of metals in different fields, spanning from industrial sectors to construction materials to surface treatments for cultural heritage.

This Special Issue is oriented toward all corrosion issues associated with the fundamentals of the corrosion science of metals, alloys, and materials; corrosion protection; and testing to assess corrosion resistance. Subjects of interest include the corrosion behavior of metals and their alloys. The development of methods to prevent and control the corrosion of metals and their alloys is also of interest.

I am pleased to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

In the present investigation, the corrosion tendency of mild steel under acidic pH was studied by employing unused expired amiodarone (EAD) drug as a potential corrosion inhibitor by adopting the weight loss measurement method. The corrosion inhibition efficiency (IE) of the formed protective film (EAD) on the steel surface was analyzed using potentiodynamic polarization and AC-impedance spectroscopy studies. The surface morphology of the mild steel before and after corrosion (in 1.0 M HCl) was analyzed via scanning electron microscopy–energy dispersive X-ray spectroscopy (SEM–EDAX), atomic force microscopy (AFM), and thermodynamic studies. The weight loss measurement under different concentrations of EAD indicated that an excellent inhibition was displayed at a concentration of 0.001 M, and the IE was found to depend on both the concentration and molecular structure of EAD. A potentiodynamic polarization study revealed that EAD predominantly acted as a cathode inhibitor, and electrochemical impedance spectroscopy (EIS) confirmed the adsorption of EAD on the surface of mild steel, which obeyed Temkin’s adsorption isotherm model. The calculated thermodynamic parameters revealed that adsorption was spontaneous and exothermic. Full article
