Numerical simulation of the ceramic core manufacturing in the investment casting process
Kinc, Marek ; Kováč, Marek (referee) ; Tomek, Ladislav (advisor)
The aim of this diploma thesis is validation of numerical simulation of the ceramic core manufacturing in the investment casting proces. The first part submit the theoretical description of the manufacturing of the ceramic cores and a description of the basic principles of numerical simulations. The second part compares the video recording of filling the wax-ceramic mixture to the die-casting mold and simulation of the same process created in a simulation software Cadmould 3D-F.
Interaction of melted nickel alloys with materials of ceramic cores
Feller, Šimon ; Pernica, Vítězslav (referee) ; Záděra, Antonín (advisor)
This study focuses on the interactions between the IN713LC alloy and various oxide ceramics and oxide coatings commonly used for casting applications in the aerospace or medical industries. The investigated ceramics are based on SiO2, ZrO2, ZrSiO4, Al2O3 and Y2O3. An experimental design proposed for the purpose of this study produced samples used to examine the chemical composition of the metal-oxide ceramic interface. This study compares the findings from the samples with assumptions derived from thermodynamic calculations or thermodynamic conclusions stated in scientific articles with similar themes.
