Abstract
Abstract The corrosion of the low alloy steel A508-alloy 52 M interface region in buffered and non-buffered chloride containing solutions was studied by using the scanning vibrating electrode technique (SVET), scanning ion-selective electrode technique (SIET), and time of flight secondary ion mass spectroscopy (ToF-SIMS). The typical pit in low alloy steel {A508} formed in NaCl solution was stopped immediately when {H3BO3} was added to the NaCl solution, and the pit became cathodic. With increasing immersion time, {H3BO3} entered into the pit, and the corrosion of {A508} became general corrosion.
