... rate of carbon steel was accelerated significantly and finally was determined by the limiting diffusion rate of oxygen. Originality/value – A corrosion model of rusted carbon steel was established, suggesting that iron rust formed in all slightly acidic waters with low alkalinity probably...

...Layla A. Al Juhaiman; Amal Abu Mustafa; Wafaa K. Mekhamer Purpose The purpose of this paper is to study the corrosion inhibition of carbon steel (CS) using a “green” inhibitor, polyvinyl pyrrolidone (PVP), in an aerated, alkaline medium containing 0.1M NaCl (blank) at pH 9 and pH 10. The effects...

...Shobha Manikandan; Jagannath; V.K. Shrikhande; G.P. Kothiyal Purpose To study the degradation behaviour of borosilicate glass, which is suitable for hermetic sealing with Molybdenum and Kovar (Fe/Co/Ni) alloys, as a function of concentration and temperature in both acidic and alkaline media...

...S.A. Umoren; I.B. Obot; E.E. Ebenso; P.C. Okafor; O. Ogbobe; E.E. Oguzie Purpose To investigate the inhibitive effect of gum arabic (GA) for the corrosion of aluminium in alkaline (NaOH) medium and determine its adsorption characteristics. The present work is another trial to find a cheap...

... (open circuit potential and potentiodynamic polarization measurements) and scanning electron microscopy. Findings The formation of passive films on iron electrodes immersed in weak‐alkaline phosphate solutions was found to occur in three main steps, being the Na₂HPO₄...

... of steel against corrosion. Some parameters even indicated a detrimental action, particularly as the alkalinity of the solutions increased. Therefore, the application of this type of coating cannot be recommended during repair procedures of reinforced concrete structures due to the extremely alkaline...
