Assessment of corrosion degradation in materials
Plichta, Lukáš ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
The work describes the principle of degradation of corrosion in materials, specifically metals and their alloys. Corrosion is divided into several aspects. The fundamental division according to its origin divides this phenomenon into chemical, electrochemical and biological corrosion., It distinguishes between uniform, non-uniform, spot, selective, crevice, erosive, intercrystal corosion and corrosion cracking according to corrosion damage. It also presents corrosion testing options. In the experimental part, it describes the production of samples from gray cast iron, their dimensions, applied surface protection, hardness measurement and roughness measurement. This work also conducts electrochemical tests and tests in a condensation chamber on selected samples of gray cast iron GJL-250MnCuCr.
