Topographical lines and maps as well as chronoamperometric plots were measured during operation in the feedback mode. Next, the release of metal ions at the anodic sites and the consumption of oxygen at the cathodic sites developed in holidays could be monitored during operation in the generator-collector mode. Furthermore, the surface topography of defective coatings was imaged by using the redox competition mode YR 2010 FD 2010 LK http://riull.ull.es/xmlui/handle/915/19118 UL http://riull.ull.es/xmlui/handle/915/19118 LA en DS Repositorio institucional de la Universidad de La Laguna RD 27-may-2024
