Piston Rings of Modern Petrol Engines
Cupák, Václav ; Maršálek, Ondřej (referee) ; Raffai, Peter (advisor)
This bachelor thesis deals with issues of piston rings used in modern petrol engines. The first part is focused on describing of functions and requirements with which piston rings must deal with. Next part is aimed on shapes of piston rings. Materials from which are piston rings made of are part of third chapter. For proper function, it is important to make some surface treatment. The last chapter contains surface treatment of piston rings.

Design of paint systems in coachwork parts of easel issues
Fajfr, Jan ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This bachelor thesis deals with proposal for a new type of painting. There is a solution of proper pretreatment for undercoat. Teoretical part includes analysis of these pretreatments, types of powder coatings, options how to apply these coatings including curing. There have been made samples for the purpose of this work and the samples were tested for resistance. Conslusion of this work contains results of the experiment and the choice of the best type of painting with regards of economy.

Surface treatments of internal combustion engines cylinders
Malec, Petr ; Raffai, Peter (referee) ; Maršálek, Ondřej (advisor)
This bachelor thesis is a professional research, which describes the most common methods of surface treatments of modern internal combustion engines cylinders. The work consists of the distribution of the species changes, their use and justification of their application. It also describes the technology of individual surfaces, their coating and finishing operations to achieve the best results of sliding surface.

Surface treatments of parts internal combustion engines
Toman, Josef ; Novotný, Pavel (referee) ; Maršálek, Ondřej (advisor)
This bachelor thesis is a professional research dedicated to the most frequently used surface treatments, applied to the stressed parts of internal combustion engines. The thesis also refers to surface treatments classification, benefits for the automotive industry and reasons for their development. Further it focuses on definitions of the technologies used, characteristics of processes and coatings, finishing operations after surface treatments and application of these treatments on the parts of internal combustion engines.

Influence of surface treatments on the quality of molded parts
Okurka, David ; Dvořák, Milan (referee) ; Hušek, Martin (advisor)
This thesis examines the influence of surface treatments on the quality of molded parts. At the beginning of this work explains why the finish and what are the current demands on the development of manufacturing technologies. It further describes the most common surface treatment of metals, which are currently very often occur. The next section is divided into forming the surface and volume and describes the different types of species-forming, such as cutting, bending, drawing, etc. At the end of the work described cooperation with the Hettich ČR, k.s. and Tokoz, a.s.

Surface treatment of roll bearings
Kubelka, Milan ; Klakurková, Lenka (referee) ; Švejcar, Jiří (advisor)
The bearings are one of the most widely used construction components enabling mutual movement of parts and at the same time transmission of interacting load. The basic requirements placed on components of roll bearings are particulary increase of contact fatigue resistance, decrease of the friction coefficient between the rolling bodies and bearing rings, increase of hardness and abrasion resistance of functional surfaces, the wear resistance, corrosion protection and finally the electrical and optical properties too. As production of bearings from materials with these attributes would be quite expensive, surface modifications are used for improving the mechanical properties. The main task of this bachelor thesis is description and evaluation of technologies suitable for surface treatment of roll bearings with increased attention to those types of surface treatment which, in cooperation with SVÚM will be studied in more detail in the experimental part of this work (especially polymer coatings, phosphate films and DLC - type coatings). The wear evaluation of different types of coatings was performed with the aid of scanning electron microscopy after the tribological testing.

Surface treatment of furniture hardware
Fiedlerová, Eva ; Vyplašil, Evžen (referee) ; Kubíček, Jaroslav (advisor)
The thesis is concerned with surface treatments with application of furniture hardware. Furniture hardware is interacted by outsider factors which must be eliminate by proper part of surface. Befor surface treatment it self part of surface have to be clean. Surface treatment is choose in dependence on final look of part. Selected representative is door knob and product and technologic procedure of surface treatment are describe in this sample.
