Application of Modern Technology for Manufacturing of Prototype Model of Fixation Handle of Keyboard Stand
Rozum, Jakub ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
This thesis is focused on manufacturing of prototype model of fixation handle of keyboard stand using modern vacuum casting technology. The first chapter is focused on product analysis. The following parts of the thesis consist of research dealing with issues of vacuum casting and materials used for this technology, especially casting resins. Part of the thesis is manufacturing of a silicone mold based on already existing component, which is used for the casting of the new component. The silicone mold is made of a silicone mixture Silastic T – 4, for the casting of the new component is selected casting material SG 2000 / Komp. A + B. For vacuum process is used vacuum chamber MK Mini. Bachelor thesis is completed by technical and economic evaluation.

Chemical-heat treatment of steels
Rozum, Jakub ; Pokorný, Zdeněk (referee) ; Sedlák, Josef (advisor)
This thesis deals with study of surface layers of low-carbon steels formed by chemical-heat treatment. The first three chapters consist of theoretical part of the thesis, there are explained basic physical principles of these technologies and described individual types, the third chapter deals with the application of chemical-heat treated low-carbon steels in mechanical engineering. The experimental part of thesis deals with analysis of surface layers of two low-carbon steels formed using plasma nitrocarburizing and gas nitrocarburizing. The properties of these layers are evaluated based on the results of mechanical tests (hardness tests) and observation of microstructure. The thesis is completed by discussion, where the achieved results are evaluated.
