Electrochemical and theoretical investigation for some pyrazolone derivatives as inhibitors for the corrosion of C-steel in 0.5 M hydrochloric acid

Investigation of Anticorrosive Property of Carbazolecarbaldehyde Azine on Mild Steel Using Electrochemical, Morphological and Theoretical Studies

“…Though techniques such as selection of appropriate material and suitable design, surface treatment, anodic and cathodic protection, applied and reactive coatings, plating are employed to defend metals and their alloys from corrosion, the usage of corrosion inhibitors is the best among all. Organic small molecules which include more number of polar groups, heteroatoms, aromatic rings with π electrons and unsaturated bonds in their molecular structure are widely utilized as inhibitors in industrial sectors for various metals, especially MS because of their effectiveness in wide temperature ranges, material compatibility, good solubility, low costs and relatively low toxicity [5][6][7][8][9]. These inhibitors can easily adsorb onto the material physically or chemically through electronic interactions to form protective film, which displace water and protect it from deterioration [10][11][12][13][14][15].…”

Multifunctional Aspects of the Synthesized Pyrazoline Derivatives for AP1 5L X60 Steel Protection Against MIC and Acidization: Electrochemical, In Silico, and SRB Insights

“…The OCP plots reached a steady-state area after a rapid increase in the negative direction of the potential, where it implies that an equilibrium state at all concentrations of the added Pz series inhibitors was achieved between both the oxidation and reduction processes with a zero bias potential. 10 The behavior of both the blank and other inhibited samples was nearly the same in terms of the direction of the OCP or the values of the E OCP , where the differences were no more than 85 V and were comparatively within the same range of the listed E corr values in Table 3 . 10 This signifies the ability of Pz series molecules to inhibit both the cathodic and anodic reactions and they can be designated as mixed-type inhibitors.…”

Enhancing the inhibition and adsorption performance of SABIC iron corrosion in sulfuric acid by expired vitamins. Experimental and computational approach

“…For this reason, scientists have tended to solve this major problem in different ways, and one of these ways is the use of corrosion inhibitors. [1][2][3][4][5] Several synthetic organic molecules [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] were utilized to inhibit the corrosion of iron and steel in strong acidic media. Usually, these molecules containing heteroatoms and multiple bonds.…”
