EU Electrochemistry of Surfaces and Interfaces - 5PUPESIN

Goal(s)

Corrosion:
Build on the concepts covered in the first year of the master’s program
Understand the different types of corrosion: corrosion-mechanical-environmental coupling (intergranular corrosion, stress corrosion cracking, hydrogen embrittlement), and hot gas corrosion.
Understand the different types of surface treatments (coatings, conversion treatments, diffusion, and structural transformations).
Expand on corrosion analysis techniques: impedance spectroscopy, material characterization techniques.
Understand how to integrate environment, materials, and protective solutions

Microsystems:
Address specific aspects of electrochemistry applied in the microelectronics and microsystems industry. The focus is on deposition processes, to illustrate how judicious use of electrochemical processes can solve the specific challenges of this field.

Interfacial electrochemistry:
Address complex aspects of real electrochemical interfaces: the role of the double layer, complex redox mechanisms, and spectroscopic methods coupled with electrochemistry.
