Plastic plating
Čermák, Jan ; Kubíček, Jaroslav (referee) ; Žák, Ladislav (advisor)
The perspective of the production of plastic parts has helped to spread the metallization of these parts on a large scale. Whether a coating is functional or just decorative. This bachelor thesis presents a comprehensive study, analysis, evaluation and comparison of the possibilities of creating metal coatings on plastic materials. The thesis deals with galvanic, chemical, vacuum and special methods of plating. For all the mentioned methods of plating, the technological procedure, equipment for plating, evaluation of individual methods and analysis of the use of plated plastic parts are given.

The block of flats
Kubíček, Jan ; Pilík, Václav (referee) ; Benešová, Romana (advisor)
This bachelor's thesis is focused on construction of an apartment building in quiet area of the town of Prostějov. Its appearance and purpose fit into the surrounding buildings. The free-standing object is a partially basement, it has parking space and approximately shape of rectangular. The apartment building is designed as a 4-storey building with one underground floor. There is a separate cellars for each of apartment unit in the basement. There are sixteen residential units in four floors, always 4 residential units per floor. Flat units have its own entrance to private terraces on the ground floor and to balcony in upper floors. The building is based on concrete foundation strips and is covered with a warm flat roof. The load-bearing system is a two-way wall system and is lined with ceramic blocks. Horizontal structures are cast-in-place reinforced cncrete. The vertical connection is ensured by a three-arm staircase that wraps around the elevator shaft. The work is developed to the level of project documentation for the construction.

Animation on the Periphery
Hanáková, Veronika ; Czesany Dvořáková, Tereza (advisor) ; Kubíček, Jiří (referee)
The thesis attempts to precisely describe the production of animation in the context of the state- socialist mode of production. Through the question of "autonomy" for cartoons and puppets films in the era of Kamil Pixa (1969-1985), we will try to specify the position of animation within the re- centralized organization and dramaturgical section in the Short Film. In the context of the normalization period, animation had a different position and function compared to the feature films. Using the example of a studio in Čiklova Street, we outline a model of making a puppet film that was more like a "craft workshop" that retained its notional autonomy as long as it had its own space.

Renovation of wood flaker rotor blades by flux cored wires
Soldán, Jan ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
The bachelor thesis presents a state of renovation of wood flaker rotor blades by flux cored arc welding. The theoretical part of the thesis presents posssible ways of renovations with materials included. Subsequently, in order to find out, which one of two flux cored electrodes are more suitable for this specific renovation, the experiment was made. The flux cored electrodes were compared in heat input, price, micro and macro structure and final hardness of welded material. Due to very high hardness results, the flux cored electrode named Megafil A760M was chosen to be used in the renovation. At the end of the thesis, the specification of welding process was according to EN ISO 15 609-1 standard.

Application of WC grains by brazing
Izák, Josef ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
Bachelor thesis is aimed to assessment condition of brazing component barking plate. Solder contains grains of tungsten carbide is applied on steel due to raise hardness of plate. Applied solder with grains, does not only raise the hardness, but also multiply increase lifetime of plate. Technology, which is used to brazing, is oxy – acetylene flame. It will be examined two type of solder. In the first it is provided optical exam and then destruction exams (micro hardness, macrostructure, microstructure, SEM and EDS analysis). In the end It was proposed qualifications of brazer and exams of brazing join.

Welding of pipes made of CrMo steel
Matějek, Martin ; Sigmund, Marian (referee) ; Kubíček, Jaroslav (advisor)
The aim of this diploma thesis is to compare mechanical properties of welded joints on tubes from 32x2 mm. Tubes are made from 25CrMo4 steel, which is used for production of racing kart chassis. The steel has a tensile strength of Rm = 800 MPa and up to 1200 MPa after refinement. For welding of samples are used technologies MAG and TIG.

CMT advanced application in industrial practice
Šoulák, Petr ; Sigmund, Marian (referee) ; Kubíček, Jaroslav (advisor)
In presented diploma thesis is studied problematics of welding of high strength steels. This work also describes arc welding in protective atmosphere CMT Advanced. In experimental part of this work is CMT Advanced method compared with conventional arc welding in protective atmosphere in shortcut mode used for welding of Hardox 450 and Weldox 700 E. Comparing of mechanical properties of weld material are realized via transverse tensile testing and measuring of microhardness. Macrostructure and microstructure of weld was evaluated too. In the last part of this thesis is a brief economical assessment of both studied methods.

Stick welding carbon and high-alloy steels
Hendrych, Marek ; Vaněk, Mojmír (referee) ; Kubíček, Jaroslav (advisor)
This thesis deals with analysis of manual metal arc welding method or method 111. In the research part of this thesis are discused principles of this method, welding power sources and additional welding material-coated elecrodes. Further the thesis is focused on the weldability of steels, especially carbon steels and austenitic stainless steels. In the experimental part was accomplished measurement of operational characteristics of coated electrods. Measurement was carried out on sample of cabon steel S235JR according to ČSN EN and austenitic stainless steel X5CrNi18-10 accordig to ČSN EN. The evaluation envolves a comparison of the results and their justifications.
