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.
