Optimalization of arc spraying parameters
Šildberger, Radek ; Filipenský, Jan (referee) ; Kubíček, Jaroslav (advisor)
The project elaborated as a part of engineering studies branch M2307: Engineering Technology, Specialization 02: Forming and Welding Technology deals with the optimization of arc spraying parameters for TAFA 9935 facility.The theoretical part presents the principle of arc spraying, the description of the technological process and the types of additional materials. The practical part proposes the diffrent possibilities of TAFA 9935 arc spraying facility and the suitable additional materials. Several samples with diffrent parameters of spraying were created in order to test and analyse the coating quality.

Application of plasma arc in technical practice
Bednář, Šimon ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
The first part of the thesis is devoted to research of technology which use plasma arc, as cutting, thermal spraying, surface heat treating and welding, the great emphasis is putted on the technology of welding. Second part of it is devoted to assessment of welds/joints which are made by TIG method and by PLASMA. At the welds/joints is assessed the total amount of heat input and the course of hardness in the cross section. At the welds/joints that were made by PLASMA was determined percent of dilution.

Repair of machinery
Teplý, Miroslav ; Kovář, Petr (referee) ; Kubíček, Jaroslav (advisor)
Theme of this Bachelor´s thesis deal with problems of repair of machinery - repair the shaft. The thesis is divided into two parts. The first part deals with the possibility of using thermal spraying for the renovation of the shaft surface at the point of contact with the shaft seal ring. The second part deals with the use of epoxy putty for the renovation of the shaft surface at the imposition of a bearing.

The use of surface modifications in recent technical practice
Červinka, Martin ; Čelko, Ladislav (referee) ; Klakurková, Lenka (advisor)
Bachelor's thesis deals with problems of surface treatment materials and their basic division. Work is detail focused on technology of thermal spray coatings. This work summarizes the basic information about the technology thermal spray coatings, their features and an overview of methods for their production. The aim of the project is to create an overview of methods of surface modifications used in recent practice and their application in different branches of industry.
