Corrosion and Protection of the Metallic Materials

Instructor:Assoc. Prof. Ilya Bardin

Course Summary

The course “Corrosion and protection of metals” has applied orientation. This discipline contains fundamentals of gaseous and aqueous corrosion. The course discusses the following main areas of corrosion science:

  • Gaseous corrosion: thermodynamics and kinetics of high-temperature corrosion in gases, mass transfer in the continuous oxide films, classification of oxide films, oxidation of alloys, theories of heat resisting alloying.
  • Aqueous corrosion: double electric layer and electrode potentials, mechanism of electrochemical corrosion of metals, polarization of electrode processes, aqueous corrosion reaction mechanisms, calculation of electrochemical corrosion processes, multielectrode systems, passivity. Forms of aqueous corrosion: uniform corrosion: aqueous corrosion, atmospheric corrosion, subterranean corrosion, marine corrosion, galvanic corrosion, stray-current corrosion, molten salt corrosion; localized corrosion: pitting corrosion, crevice corrosion, filiform corrosion, intergranular corrosion, knife-line attack, stress-corrosion cracking. Methods of protection against aqueous corrosion.
  • Methods of corrosion research: methods for measuring gaseous and aqueous corrosion rates. Corrosion tasting and evaluation.

Laboratory practicum involves nine laboratory works according with course of lectures using modern laboratory equipment.
