Corrosion and inhibition of stainless steel pitting corrosion in alkaline medium and the effect of Cl− and Br− anions

Electrochemical behavior of 304L stainless steel in high saline and sulphate solutions containing alga Dunaliella Salina and β-carotene

“…Multi-step pickling in successive HCl and HF electrolytes allowed achieving a smooth surface finish free of any oxide scales. The effect of carbonate anion on the pitting corrosion and inhibition behavior of stainless steel samples has been studied using potentiodynamic and scanning electron microscopy techniques [23]. Additions of Cl − or Br − ions into the carbonate solutions increased the anodic dissolution rate and decreased the pitting corrosion resistance.…”

Classic and local analysis of corrosion behaviour of graphite and stainless steels in polluted phosphoric acid

“…It was shown that chloride and sulfide ions accelerated the anodic process by altering passivity and activating the material dissolution rate. This harmfull effect was attributed to the adsorption of ions on the material surface [8][9][10][11][12][13][14][15][16].…”

Modeling Corrosion Reactions of Steel in a Dilute Carbonate Solution

“…The corrosion reactions in these conditions are considerably intertwined, electrochemical, and chemical, during which the cathodic reduction, anodic dissolution, and passivation are relatively similarly sensitive to the chemical composition of the environment and the metallurgy of the steel ( . Carbonate affects the aqueous equilibrium as it raises the pH, generates bicarbonate, and restricts the roles of the dissolved oxygen (Ref [12][13][14]. It affects the transport and reduction mechanisms of water, oxygen, and hydrogen protons, and gets adsorbed onto the surface to oxidize the steel, raise the local alkalinity, and form Fe(OH) 2 , FeCO 3 , and other intermediate products as green rust (Ref [15][16][17][18].…”
