Summary

The study of electrochemical corrosion has complex nature and follows the students´ previous knowledge of chemistry, physics (thermodynamics and kinetics), materials science and technology. In this subject the student gains theoretical as well as practical knowledge of corrosion processes and protection methods, especially under atmospheric conditions and water environments. The attention is also paid to the localized types of corrosion: pitting, crevice, intergranular, stress corrosion cracking and corrosion fatigue. In chemical corrosion, the specific types of corrosion in gases at higher temperatures, including destruction by hydrogen. The study of corrosion protection is aimed at materials selection with respect to environment severity, at surface treatment, electric (cathodic) protection, inhibitors and structure design. The student is also acquainted about standard methods of testing and evaluation of material resistance to corrosion.
