E-SVET describes a novel, Environmentally controlled, Scanning Vibrating Electrode Technique which allows the measurement of localised corrosion current flux under conditions of low oxygen partial pressure. E-SVET replicates the low oxygen partial pressure conditions which occur inside a food can. SVET was utilized to investigate rapid detinning processes initiated in the presence of aerated fruit acid. In this investigation, two corrosion mechanisms were detected; de-tinning on the outer surface of the coating, followed by localised pitting on the iron-tin alloy layer. Corrosion pits were subsequently characterized using White Light Interferometry, a practical method for obtaining detailed information on the geometry of the corrosion pits.
