The subject is focused on the fundamentals of corrosion processes, mechanisms and species. The subject makes inquiry into the factors that influence the velocity and course of corrosion in technological enviroment and especially from the point of view of conditions in energetic run. In independent chapter there are clarified specific corrosion danger in nuclear energetics. The study includes the methods of corrosion protection and effects of energetics on living environments.

Students will be able to: Understand the mechanisms of corrosion processes and methods of corrosion protection against corrosion in the work of different environments. Understand the most important area of corrosion types occurs not only in energetic machinery. Understand the influence of temperature, exert- fatigue and choice of materials in working environments in technological practise from the point of view of energetic operation - work.
