Course objectives

The objective of this course is to achieve a knowledge about fundamentals of corrosion processes and corrosion protection, and methods of corrosion testing and prevention. This course will provide student to acquire an orderly pattern of thought in solving practical corrosion problems in a critical and creative manner.

Course enrolment requirements and entry competences required for the course

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

By the end of this course, students will be able to:
- define and classify the corrosion processes
- evaluate the resistance of materials for any given conditions
- perform the corrosion tests
- ascertain and select the most effective corrosion protection system for any given conditions – project related and on-site if appropriate – and evaluate its durability
