Grupo de Investigação

SECOP-Surface Engineering and Corrosion Protection Group

Prof. Mario Ferreira is leader of the Surface Engineering and Corrosion Protection group. SECOP holds an extensive experience in the field of anti-corrosion coatings for metal alloys. The group is currently working on complementary areas, including the development of micro and nanorecipients for encapsulation of corrosion inhibitors, to provide a controlled and prolonged release of the inhibiting species for self-healing coatings and the investigation of corrosion inhibition and self-repairing processes at micro-/nano-level by localized electrochemical techniques.
