The subject is focused on the fundamentals of corrosion processes, mechanisms and types of corrosion attack, factors influencing corrosion in power industry, including nuclear power. The study includes the methods of corrosion testing, monitoring and protection.
Aim of the course -
Last update: Fialová Jana (17.01.2018)

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.
