Galvanizing of steel components
Turkovič, Matúš ; Hanusová, Petra (referee) ; Zelený, Martin (advisor)
This thesis deals with galvanic, i.e. electrochemical plating. It is concerned with chemical and physical principles that accompanying plating followed by general overview of metal coatings as well as describes the process of their application. In detail, it is focused on nickel coatings. Part of the work is focused also on practical deposition of such coatings on steel samples as well as on study of effects of plating conditions on prepared coatings.

Využití zinkových povlaků pro antikorozní ochranu ocelových součástí
Straka, Dominik
This Bachelor thesis „Use of zinc coats for anticorrosive protection of steel components“ characterizes corrosion and its effect on steel materials when being in a corrosive environment. Moreover, it categorizes corrosion and defines various methods of how steel materials can be protected against it. Special focus is given to protection using metal coats with lower electrode potential than Fe. Furthermore, this thesis determines particular methods of how to create metal coats depending on the type of material. Especially, the use of zinc applied by the hot-dipped and galvanic method is discussed. Quick laboratory tests are identified as a suitable method in order to evaluate the quality and resistance of created coats. Finally, lifespan and corrosive resistance of each coat are assessed considering the environment in which these coats are exposed.

Antikorozní ochrana ocelových součástí pomocí kovových povlaků
Vyškovský, Josef
This work focuses on evaluation of mechanical and anticorrosive properties of zinc coatings. Work as a first characterizes kind of corrosion and possibilities of corrosion protection measures. For the purpose of the experiment, test samples representing a cross-section of current methods of corrosion protection using zinc coatings were prepared. Mechanical properties were evaluated by bend testing and the Erichsen method. Corrosion test specimens were tested in a corrosion chamber. An electron microscope was used for more detailed structural analysis. Electron microscope elemental analysis of selected coatings was also included. Based on the information obtained, it proposes a suitable solution in practice, depending on use of the plated component.
