The scanning vibration electrode technique (SVET), providing a map of the current density, allows demonstration of the termination of the corrosion process under irradiation. Fig. 2a shows the corrosion current map recorded after 36 h of immersion of the SiOx ZrOx film with IR-laser light sensitive BSA-loaded nanocontainers Ti02 Ag/PEI/PSS/PEI/PSS. Before immersion, the film was... 

The scanning vibrating electrode technique (SVET) uses a microelectrode capable of measuring potential gradients in the corrosion solution near localized corrosion. It locates and measures corrosion at specific points of the corroding surface [9]. This technique performs in situ locahzed corrosion measurements occurring on the surface. During the measurement, the microelectrode vibrates perpendicular to the surface. The tip of the...

The earliest forms of SECM experiments were carried out in the potentiometric mode. Evans reported how he used a traveling reference electrode to map equipotential surfaces in solution and calculate corrosion rates on a water pipeline. Isaacs and coworkers revived the idea in 1972 and coined the acronym SRET for scanning reference electrode technique. Instruments used to be homemade, often with rudimentary traveling devices such as the arm of an X-Y recorder and the spatial resolution was at best submillimeter. A computer-controlled instrument was commercially produced by Uniscan Instruments with a spatial resolution around 20 pm. The SRET has now been superseded by the scanning vibrating electrode technique, known as SVET, which achieves higher spatial resolution and improved sensitivity. A SVET manufactured by Uniscan Instruments is now commercially available from Uniscan Instruments and Princeton Applied Research.

Scanning Vibrating Electrode Technique (SVET) measurements of the localised corrosion activity in artificial micro-defects supported the insights gained from the drop test. Figure 2.10 shows SVET maps of samples with a non-inhibited sol-gel coating as a pre-treatment coated with a non-inhibited primer, with primer doped with MBT enclosed in capsules, and with a chromate-containing primer. After 1... 

Because cut edges are crucial areas of coil-coated material and can be used to study the effect of pigments in organic coatings on the corrosion in defects, they have been extensively studied by means of different electrochemical techniques such as electrochemical impedance and scanning vibrating electrodes [102, 139,140].
