“…Basically, the most popular steel used by companies is the mild steel; it is also usually the cheapest option, making it a great choice for industrial projects [1][2][3][4][5]. That's why it is easily exposed to the phenomenon of the corrosion due to the use of the acid solutions (HCl and H 2 SO 4 ) in several industrial processes such as cleaning and descaling [6].…”

The inhibition efficiency of 1,5-Diaminonaphthalene (1,5DNA) compound was studied by itself as well as in a mixture that included sodium chloride (NaCl), noted [1.5DNA][Cl − ], for mild steel in 0.5 M sulfuric acid. Gravimetric, electrochemical techniques and computational chemistry calculations were utilized for the assessment of corrosion inhibition efficiency and explanation of the mechanism involved during the corrosion inhibition process. The results show that inhibition efficiencies on mild steel increase with increase in concentration of the inhibitor and enhancement in inhibition efficiency was observed on addition of sodium chloride due to synergism. This inhibition has been attributed to the stabilization of adsorbed inhibitor film and, consequently, increasing its inhibitive properties. The [1.5DNA][Cl − ] acts as mixed type inhibitor and the Nyquist curves show that with the increase in the concentration, the charge transfer resistance R ct increased. In addition, [1.5DNA][Cl − ] obeyed Langmuir monolayer adsorption isotherm. Moreover, Molecular Dynamic Simulations and DFT calculations showed that [1.5DNA][Cl − ] owned a higher adsorption ability.

“…22. Graphene oxide has been studied as an excellent impermeable barrier layer on iron and SS alloys; [98][99][100][101] in the graphene oxide edge functional groups, such as carbonyl, hydroxyl and carboxylate, free electrons increase the chemisorption on the alloy surface. This attributed negative charge on the graphene oxide could repel electrolyte ions.…”

“…This method has been applied in controlling corrosion, assessment of localized corrosion, study of organic coatings, and assessment of inorganic anticorrosive pigments. In recent years, EN has been used to study the inhibition effect of different organic inhibitors such as azoles and imidazoline derivatives, amino acids and drugs in acid solutions [8][9][10]. In addition, types of inhibitor adsorption and isotherms and pitting behavior of metals were investigated by EN [8][9][10].…”

Different theoretical, electrochemical and surface techniques were applied to study the corrosion inhibition effects of 2-Amino-6-hydroxybenzothiazole in 5% HCl solution. The density functional theory was carried out and quantum chemical factors like the energy gap, energy of highest occupied molecular orbital, the energy of lowest unoccupied molecular orbital, the fraction of electron transferred, and Mulliken charges have been calculated. In addition, according to quantum calculation, S atom in 2-Amino-6-hydroxybenzothiazole indicated more tendency for electrophilic attack in adsorption. The main reason for high inhibition efficiencies in very low concentrations is the planar and simplicity of inhibitor structure which leads to increasing the efficiency of adsorption by functional group especially sulfur. Electrochemical frequency modulation and potentiodynamic polarization indicated that this material has excellent inhibiting features in very low concentrations. The influence of DC trend on the explanation of electrochemical noise data was evaluated by polynomial fitting and the optimum polynomial order m=4 was obtained. Noise resistance and the inhibition efficiency was calculated and compared in different methods. The theory of shot noise in frequency domain was used to obtain the electrochemical event charge. The corroded surface of steel in the absence and existence of thiazole compound was studied by Atomic force microscopy.
