Obrábění keramických materiálů frézováním / On the milling of ceramic materials

Rudel, Václav January 2015 (has links)
In the diploma thesis dividing of ceramic materials is made, their bonds and other attributions, which define ceramic materials. There is also described how ceramic materials are manufactured and the thesis is including information about machining ceramic materials. In the experimental part sample of ceramic material R-S67K was machined by milling. During the experiment cutting forces were measured and roughness of surface after finishing, these data were finally evaluated.

Testování a hodnocení vlastností keramických jader pro technologii vytavitelného modelu / Testing and evaluation of ceramic core properties for investment casting technology

Tirala, David January 2021 (has links)
Production of top quality castings for applications in energy, aerospace and medical industries by the addition of ceramic cores to investment casting presents many metallurgical and technological problems. Ceramic cores applied in investment casting are subjects to many requirements in terms of their inertness to the casted alloy and at the same time to their final removal from the casting cavity in such a way that does not damage the casting. Both of these assumptions can be achieved by applying a thin layer of inert oxide ceramic coating to the surface of a ceramic core, made out of a chemically removable – leachable oxide ceramic.

Environmentálně vyspělý domov důchodců / Environmentally advanced retirement home

Voves, Martin January 2022 (has links)
The subject of my master's thesis is the design of an energy-efficient house for the elderly. The building has three floors. The construction system is made of ceramic blocks filled with glass wool. The building is covered with a flat vegetation roof. The retirement home has 15 apartments, a doctor's office, a common dining area, a common room and offices for administration. A technical concept for the building environment was designed for the building. The dining room, office, lounge and doctor's rooms are forcibly ventilated. The premises are divided into three zones and each zone has its own air handling unit. Heating is provided by two condensing gas boilers and the whole building is heated by radiators. An assessment was made for the design of photovoltaic panels. In the third part, an assessment and research of sources for heating and hot water was prepared.

Fáze ženy (instalace plastik z kombinovaného materiálu). / Women's stages (mixed media instalation)

DIVIŠOVÁ, Olga January 2009 (has links)
The work deals with the theme of women's life through the stages it passes on its way to the conclusive process of ageing and dying. It tries to study this fenomen through the structure, shape changing and sarcolysis that permeates the cycle of human life.

Efektivní obrábění nových konstrukčních keramických materiálů / Effective machining of advanced structural ceramics

Jurán, Antonín January 2009 (has links)
The objective of this diploma thesis are new design materials in a view of their structure, properties, manufacture,partitions, applications and possibili-ties of effective machining them Ceramics are used in the field of design applications more often than before. They are in form of compact parts and in form of thin coatings on the surface of metal parts. Fast development of constructive applications requires the same progress rate of machining ma-chines innovations and development of new methods of effective machining these materials, too. The aim is to produce parts of demanded shapes, dimensions and surface quality at affordable costs. Ceramics guarantee long terming durability and reliability. The evaluation of ceramics grinding tests from the point of view of cutting forces and surface quality of the machined faces are presented in the last part of the diploma thesis.

Základní škola v Moravanech u Brna / Elementary School in Moravany u Brno

Trojánek, Lukáš January 2014 (has links)
The theme of this thesis is the preparation of project documentation at the level for the implementation of the construction of primary schools in the village Moravany u Brna. In the framework of the preparatory study work has been processed the entire campus, including outdoor sports facilities, paved surfaces, parking lots and additional objects required for the running of the school. The subject of this thesis is only part of the main object SO01 elementary school and part of it and this is a three storey building with the main longitudinal structural wall system. The carrier of the walls and the ceiling structure is of reinforced concrete. The roof structure is designed as a desktop with internal drainage. The façade of the building is divided according to the floor, the first floor is addressed to the contact insulation system for cladding of ceramic straps in the second and the third floor is designed to ventilated the facade of fiber cement plates with colored solution. The subject of the proposal is to solve traffic in peace into two parking lots and the Terminal for lifting children.
