Preparation and characterization of layered double hydroxides on Mg substrates prepared by powder metalurgy
Kobzinková, Eliška ; Doskočil, Leoš (referee) ; Buchtík, Martin (advisor)
This thesis deals with the preparation and characterization of double-layered hydroxides (LDH) on Mg substrates prepared by powder metallurgy. The theoretical part deals with magnesium, magnesium powder metallurgy, and LDH coatings and methods of their preparation with a focus on MgAl-LDH. The theoretical part is concluded with a research study of current research in the field of preparation of LDH coatings on magnesium substrates and the influence of process parameters on the properties of coatings. The experimental part covers the process of optimization of MgAl-LDH on Mg samples prepared by powder metallurgy. In particular, the morphology and structure of the coatings and their elemental composition were evaluated. The evaluation was carried out using a scanning electron microscope (SEM) with an energy dispersive spectrometer (EDS). The optimized MgAl-LDH coatings were also evaluated for electrochemical corrosion properties by potentiodynamic tests in Hank's solution corrosion environment and phase analysis by X-ray diffraction (XRD).

Metallic biomaterials
Bunganič, Pavel ; Remešová, Michaela (referee) ; Horynová, Miroslava (advisor)
In this bachelor thesis the objective was to make a summary of the basic metal-based biomaterials, which are presently used. These single materials are described and its suitability for various appliacation is evaluated depending on its chemical structure and microstructure, and its mechanical and corrosion characteristics.
