S-Thiazine as effective inhibitor of mild steel corrosion in HCl solution: Synthesis, experimental, theoretical and surface assessment

Extraordinary corrosion inhibition efficiency of omeprazole in 1 M HCl solution: Experimental and theoretical investigation

“…OL is added to the corrosion solution and reacts in Q235 working face to form a protective film, which effectively protects the carbon steel against corrosion by chloride and other corrosion media 34 . The charge transfer resistance also plays a certain role in corrosion inhibition, mainly inhibiting the charge transfer, thus reducing the overall corrosion reaction 35 . When the concentration is 40 mg/L, the inhibition efficiency is as high as 96.11%.…”

“…34 The charge transfer resistance also plays a certain role in corrosion inhibition, mainly inhibiting the charge transfer, thus reducing the overall corrosion reaction. 35 When the concentration is 40 mg/L, the inhibition efficiency is as high as 96.11%. With the increase in the temperature, the charge transfer resistance and film resistance decrease but still maintain the high inhibition efficiency.…”

Insights into the Corrosion Inhibition Mechanism of Canavalia gladiata Leaf Extract for Copper in Sulfuric Acid Medium

“…Corrosion inhibitors encompass both organic and inorganic varieties. Organic corrosion inhibitors are typically composed of elements such as nitrogen, sulfur, oxygen, and unsaturated functional groups. − Organic corrosion inhibitors include synthetic corrosion inhibitors, oral drugs, phosphines, amines, and plant extracts, among others. Notably, plant extracts are particularly highly esteemed by many corrosion researchers due to their wide source and cost-effective nature.…”

The Role of Some Cationic Surfactants Based on Thiazine as Corrosion Inhibitors in Petroleum Applications: Experimental and Theoretical Approach

“… 3 , 4 It was reported in the literature that organic compounds with hetero atoms such as nitrogen, oxygen, sulfur, and phosphorus show promising efficiency in mitigating the aggressive attack of corrosive species on a metal surface. 5 , 6 These types of organic compounds act at the interface between the metal and the aggressive solution through the adsorption on metal surfaces, forming a protective layer that isolates the metallic surfaces from the corrosive environment. 7 Accordingly, the selection of this type of cationic surfactants in the present work is attributed to the presence of incorporated hetero-organic moieties, which offer more protection potential against the corrosion of steel, along with the presence of a long chain that increases the minimum area per molecule.…”

“…Carbon steel is commonly used in petroleum processing facilities for refining and marine applications, due to its mechanical properties and also from an economical point of view. , It is well-known that the metallic surfaces are suffering from corrosion, and this is leading to significant economic losses in addition to a bad environmental impact. , It was reported in the literature that organic compounds with hetero atoms such as nitrogen, oxygen, sulfur, and phosphorus show promising efficiency in mitigating the aggressive attack of corrosive species on a metal surface. , These types of organic compounds act at the interface between the metal and the aggressive solution through the adsorption on metal surfaces, forming a protective layer that isolates the metallic surfaces from the corrosive environment . Accordingly, the selection of this type of cationic surfactants in the present work is attributed to the presence of incorporated hetero-organic moieties, which offer more protection potential against the corrosion of steel, along with the presence of a long chain that increases the minimum area per molecule. − Cationic surfactants are a category of surface-active agents that dissociate in water to create surface-active cations.…”
