Corrosion resistance of surface treatments by polysiloxane paint systems.
Kulhanová, Veronika ; Molliková, Eva (referee) ; Tulka, Jaromír (advisor)
Influence of atmospheric and chemical environments on metal products leads usually to the corrosion damage. This master´s thesis deals with way to protect metals from corrosion, especially by polysiloxane coatings in combination with coatings containing zinc. Corrosion resistance of created coatings systems is tested by laboratory accelerated tests in corrosion chamber, where the natural atmospheric conditions are simulated. Chemical resistance in selected environments is verified by drop test. Quality characteristics coatings – thickness, adhesion to the underlying material, hardness and stability of the coating colour and gloss are evaluated too.

Study of properties of fibre-cement composites
Hoško, Marek ; Gromeš, Vít (referee) ; Bodnárová, Lenka (advisor)
The work deals with the summarization of knowledge concerning issues of fiber cement. There are characterized feedstock, production technologies, properties and surface finish corrugated fiber covering. Furthermore, the paper describes the normative requirements for Corrugated Sheets, affecting the quality of manufactured roofing. In the practical part of the thesis were sampled corrugated sheets, which have been investigated possible influences affecting the quality of the surface finish. Was also solved the issue of insufficient adhesion of acrylic paint on selected plates in the factory CEMBRIT a.s. in Šumperk.
