Present Research Group

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.


Teaching Activity

During the period comprised between January 2019 and January 2022, JT took over the role of Director of MSc in Materials and Biomedical devices (higher education course).
Currently, JT is the DEMaC’s responsible for the Tutorship Program from UA, which is an integration program for first year students.
In the last 5 years JT lectured a total of 15 different UCs and coordinated a total of 8 UCs in the field of Materials Science and Engineering fundamentals, surfaces, interfaces and materials degradation. Furthermore, these UCs were part of the Integrated Master in Materials Engineering (now BSc and MSc), Doctoral Program in Materials Science and Engineering, CTESP, BSc in Electrotechnical Engineering, MSc in Materials and Biomedical Devices and Aerospace Engineering.
