Objectives
The course “Corrosion and oxidation” aims to provide to the students the knowledge of metallic corrosion fundamentals in aqueous solutions and dry gases. Thermodynamics and kinetics of corrosion are focused. The main forms of corrosion and protection methods are described. The techniques for corrosion damage evaluation are also detailed.
Motivation
The cost of corrosion is estimated to nearly 3% of the GNP for the industrialized countries. Thus, the knowledge of the mechanisms of corrosion, forms and methods of protection is very important, because corrosion is present not only in industrial environment (public utilities, transport, production…) but also in our daily life.
Syllabus
- Corrosion: Thermodynamics fundamentals: Oxidation-reduction reactions. Redox equilibrium, Electrical double layer, Electrode potential, Exchange current density, Pourbaix´diagrams.
- Corrosion: Kinetics fundamentals: Polarization, Activation overpotential, Diffusion overpotential, Mixed potential theory, Passivation.
- Corrosion: Forms of corrosion. Uniform, Galvanic, Pitting, Crevice, Intergranular, Differential concentration, Selective, Stress corrosion cracking, Hydrogen embrittlement
- Corrosion: Protection against corrosion: Cathodic protection, Anodic protection, Inhibitors, Coatings
- Oxidation: Thermodynamics fundamentals: Ellingham´s diagram, Other equilibrium diagrams.
- Oxidation: Oxidation mechanisms: Defects, n-type and p-type oxides, Kinetics of oxidation.
- Oxidation: Oxidation of pure metals, Oxidation of alloys.
