Biodegradable bone implants based on iron
Müller, Petr ; Kazda, Tomáš (referee) ; Sedlaříková, Marie (advisor)
The present work deals with the comparison of the properties of metallic biomaterials in terms of their suitability for use as a temporary metal implant. In the work is judged biocompatibility of materials, they are comparing the corrosion rates and the influence of additives in the iron alloy to change biocompatibility and corrosion rate. In a part of this work is suggesting a method of preparing biodegradable metallic samples with different alloying elements and determine the methods, processes and measuring the corrosion rates. Part of this work is the chapter dealing with the function and effect of iron in the human body and any complications that may occur when a surplus caused by the release of part of the implant during its degradation or corrosion products. The outcome of this work is sort of created an iron-based samples in terms of their electrochemical corrosion potential, corrosion rate of samples exposed in various corrosive solutions, spectroscopic elemental analysis and outputs from the microscopic observation of the structures.

Survey of applications of investment casting from ferrous alloys and super-alloys
Smilovský, David ; Zemčík, Ladislav (referee) ; Horáček, Milan (advisor)
A content of this thesis is a survey of casting applications from specific alloys manufactured by investment casting. Thesis shows basic principles of investment casting method, its possibilities and advantages. It also lists a short metallurgical description of ferrous alloys a superalloys cast by this method. The main aim is on specific industrial branches, where these precise castings are used. There are specific applications of parts presented from various Czech and foreign foundries.
