Surface treatments in mechanical engineering
Čudová, Monika ; Kubíček, Jaroslav (referee) ; Žák, Ladislav (advisor)
The project was developed within the bachelor study presents experimental verification of two given varnishes. They are applied on a specially made plate. It was based on literary studies of corrosion coatings issues - coatings and practical tests. The samples were painted and tested according to the standards. The samples were tested on adhesion of varnishes, bending test and salt stray test. Finally all tests were evaluated.

Antibakteriální povrchové úpravy nábytkových dílců
Frkalová, Veronika
This thesis deals with the determination and evaluation of antibacterial properties of coatings and surface finishing. The thesis verified antibacterial, physico-mechanical and chemical properties of water-based coatings themselves with added antibacterial particles. For better orientation in issue of this thesis are generally described coatings, antibacterial substances and tested bacteria. The aim is to determine the effect on the properties of coatings with added antibacterial substances. How effective is the resistance of the tested coatings with added ingredients to the action of bacteria and fungi as well as to assess whether they are suitable for use in surface finishing furniture parts and whether they have the expected properties.

Ovlivnění adheze u protikorozních organických povlaků
Nováčková, Monika
This diploma thesis deals with the adhesion influence of anticorrosion coatings that are applied on the surface of a metallic material. The first part of the work focuses on corrosion, its division and commonly found types. The following part is aimed at protecting against such corrosion damage, including all types of anticorrosion protection. A very important part of this work is surface preparation before application of paints, which is discussed in the third part, where are described the individual methods of preparation. The fourth part deals with the anchorage profile defined and described in detail, and mentioned is also the closely related surface roughness. The subsequent anchorage profile assessment is performed by the comparison method, which consists of roughness sample ranges and follows the part defining the coating compounds, their classification, labelling as well as the colour scheme, up to their properties and methods of application on the material surface. One of the most important parts of the work is the experimental section focused on adhesion testing of the selected coatings in four types of anchorage profile using the pull-off test. The last part is an analysis of the application of knowledge about the coating system adhesion in the field of expert engineering and proficiency.
