Thermal spray coatings of bioceramics
Kašpárková, Kristýna ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
Bachelor´s thesis is focused on thermal spraying bioceramics. Bioceramic is designed to replace damaged parts of the human body. Practical use is mainly in orthopedics, jaw and facial surgery. This category of materials includes hydroxyapatite, which is characterized by biocompatibility and the ability to form a strong bond between the bone and the implant. The experimental part of the thesis was spraying 40 - pieces of dental implants for the company LASAK s.r.o. Plasma spraying technology was used to apply the hydroxyapatite coating. The required coating thickness was 60 m. The implant was sprayed and cleaned before spraying. Spraying was carried out in the laboratory of plasma coatings dental and skeletal implants ÚST FSI VUT Brno. A dimensional control was performed after plasma spraying.

Biodegradable Mg-based materials for stents and bone implants
Zemková, Mária ; Král, Robert (advisor) ; Stráská, Jitka (referee)
The bachelor thesis is focused on the effect of mechanical processing rotary swaging (RS), specifically on the microstructure, mechanical properties and corrosion properties. The investigation was performed on the magnesium alloy AE42 with a different number of RS passes, which can be useful for medical applications. RS is more efficient and cheaper alternative to different material processing methods producing fine-grained struc- ture. Fine-grain structure with grain boundaries with high angle misorientation was achieved by this process. Microstructure was inhomogeneous - the grain size decreased from the surface to the center. An improvement of mechanical properties with the increase in the number of swaging steps was observed. Processing also led to a decrease in corrosion resistance in this alloy. Microstructure development was investigated by electron microscopy scanning. Development of mechanical properties was characterized by compression deformation tests and microhardness measurements. Linear pola- rization method was used for the interpretation of corrosion resistance. 1

Modern methods of implant manufacturing by Rapid Prototyping technology
Trubačová, Pavlína ; Sedlák, Josef (referee) ; Píška, Miroslav (advisor)
This research describes the possibilities of using unconventional technologies known as Rapid Prototyping methods. These methods make part of Additive manufacturing technologies. The project investigates the influences of process parameters on the final part quality and analyses the advantages and the disadvantages of using RP technologies for medical application, mainly for implant fabrication. The objective of experimental part is fabrication of samples by Selective Laser Melting (RP technology). The stainless steel will be used and two parameters will be varied (laser power, component inclination). For final evaluation of mechanical properties, surface quality, Alicona machine, compression test and Vickers’ hardness test will be used.
