Bulk materials from oxidized powder feedstock
Luptáková, Diana ; Molliková, Eva (referee) ; Jan, Vít (advisor)
In this thesis, methods of effective aluminium powder oxidation are evaluated, such as oxidation at higher temperatures in atmosphere, anodic oxidation and oxidation during high-energy ball milling. It describes following treatment and methods creating volume sammples in such way, where ductile properties are preserved, but the process of hardening by aluminium oxide occurs.

Elimination of degradation processes of metallic thin films
Danovič, Jakub ; Šubarda, Jiří (referee) ; Šimonová, Lucie (advisor)
This work deals with issues of thin films, their behaviour in different enviroments and protection of theese films against unwanted degradation processes. Metal thin films are made by special physical or chemical methods in the presence of vacuum. Deposition is performed on properly cleaned substrate made of different materials, for example glass, ceramics or another metal. Theese films degrades under the influence of moisture, heat and other. There are several types of films on different bases made to prevent thin films against degradation.
