Status of the course

Course objectives

After completed course students will have acquired knowledge necessary to prevent corrosion and solve problems caused by corrosion.

Course enrolment requirements and entry competences required for the course

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After completed course students will be able to:
- define and classify corrosion processes
- determine the possible application of certain metallic materials in specific corrosive environments
- implement the necessary corrosion tests
- choose an adequate system of protection against corrosion under specific conditions and assess its durability
