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.
