Corrosion

Corrosion theory, thermodynamic and electrodekinetic conditions, Pourbaix diagram and polarization curves, passivity. Common types of corrosion, characteristic features, mechanisms and measures. Impact of metallurgical, physical and mechanical factors. The corrosion properties of the main structural materials. Inhibitors, cathodic protection, monitoring and measurement principles. Surface treatment for corrosion protection. Test methods

The candidate:

• Has a basic understanding of the theoretical basis of wet corrosion on metallic materials and can calculate and construct Pourbaix diagrams and overpotential curves and further use these to calculate corrosion rates or predict passivity or immunity.
• Can distinguish and describe characteristic features and mechanisms, thereby identifying different types of corrosion.
• Has an overview of various methods to reduce the likelihood of corrosion starting, such as surface treatment, cathodic protection and inhibitors and may suggest suitable methods for specific environment.
• Can plan, conduct and report corrosion tests in the laboratory.
• Can actively participate in discussions and testing in the laboratory to identify causes of corrosion-related damage and propose solutions such as alternative material choices and anti-corrosion measures also based on relevant standards.
