Tailoring of physical properties of ceramic surface by the metallic layer deposition
Dvorský, Vojtěch ; Kachlík,, Martin (referee) ; Salamon, David (advisor)
The master thesis focuses on the preparation of nickel coating on ceramic (Al2O3) substrate. The deposition of nickel was carried out by the electroless plating method in bath at various kinetic conditions. An impact of varied size, shape and roughness on the quality of the coated surface was investigated. The main goal was to find optimized conditions of the plating process of the thin metal coatings. Prepared nickel coatings were analysed by SEM, EDX analysis, mechanical profilometry and the plating bath was analysed by UV-VIS spectrophotometry. The continuous nickel coatings were achieved by modifying the deposition process, and the kinetic mechanism of experimental conditions was described.

Transparent conducting tin oxide layers prepared from inorganic precursors
Dvorský, Vojtěch ; Drbohlavová, Jana (referee) ; Dzik, Petr (advisor)
The thesis focuses on the preparation of transparent electrically conductive tin oxide layers. First, a stock sol based on inorganic precursors was synthetized. Substrates were coated with a small amount of sol by spin coating or material printing to form thin layers. By modifying the solution by adding additional substances, specific coating compositions were prepared to optimize the deposition and the resulting layer properties. Selected samples were analysed by mechanical profilometry, XRD, SEM and XPS.
