Anti-corrosion performance of dehydroacetic acid thiosemicarbazone on XC38 carbon steel in an acidic medium

3,4-Dimethoxy phenyl thiosemicarbazone as an effective corrosion inhibitor of copper under acidic solution: comprehensive experimental, characterization and theoretical investigations

“…While OCP data offer valuable insights into the corrosion behavior, it is crucial to emphasize that determining the inhibitor type solely based on OCP measurements is not conclusive. 67,68 To gain a comprehensive understanding of the inhibitor's mechanism of action, additional analyses, including polarization and EIS studies, will be essential and will be further discussed in subsequent sections.…”

“…74,85,115 Furthermore, in addition to conjugated double bonds, the adsorption process is facilitated by the active involvement of electron-rich lone pairs of nitrogen, sulfur, and oxygen. 61,68 Using a donor-acceptor contact, this partnership facilitates chemisorption and activates two crucial processes that underlie the inhibitory effect. Initially, electrons are transferred from the active sites of the inhibitor to unoccupied d orbitals of the copper atom (donation).…”

Sustainable and Green Corrosion Inhibition of Mild Steel: Insights from Electrochemical and Computational Approaches

“…7,8 One frequently used industrial acid is hydrochloric acid, which corrodes metals through chemical or electrochemical reactions. 9,10 Over time, various methods have been developed to prevent or mitigate steel corrosion, including protective coatings, galvanization, cathodic protection, antirust solutions, and corrosion inhibitors. 11−13 Corrosion inhibitors are substances added in small concentrations to corrosive environments to reduce or prevent metal reactions with their surroundings.…”

“…Steel is widely used in various industries, such as shipbuilding, petroleum, and construction, due to its availability, affordability, and strength. − However, steel is highly susceptible to corrosion in acidic environments, leading to substantial financial losses for industries, estimated to be in billions of dollars annually . Acids are commonly used in industrial processes like petroleum refining, acid pickling, industrial cleaning, acid descaling, and petrochemical operations, exposing metals to corrosive agents. , One frequently used industrial acid is hydrochloric acid, which corrodes metals through chemical or electrochemical reactions. , …”
