SECM was operated in the feedback mode by using ferrocene-methanol as redox mediator, and the sample was left unbiased at all times. The kinetic changes in the corrosion processes were monitored over time from the Z-approach curves. Furthermore, inhibitor-modified copper samples presenting various surface finishes were imaged by SECM and the scanning vibrating electrode technique (SVET), allowing changes both in the surface activity of metal-inhibitor films and in the extent of corrosion attack to be spatially-resolved. Differences in the local electrochemical activity between inhibitor-free and inhibitor-covered areas of the sample were successfully monitored YR 2012 FD 2012 LK http://riull.ull.es/xmlui/handle/915/19161 UL http://riull.ull.es/xmlui/handle/915/19161 LA en DS Repositorio institucional de la Universidad de La Laguna RD 17-may-2024
