Ni-P based coatings preparation on wrought magnesium alloys
Buchtík, Martin ; Fintová, Stanislava (referee) ; Wasserbauer, Jaromír (advisor)
The aim of this diploma thesis was summary of all steps and knowledge necessary to deposition of quality Ni-P coatings deposited on wrought magnesium alloys AZ31 and AZ61. There is the treatise about wrought magnesium alloys AZ31 and AZ61. Thesis includes its phase composition in the theoretical part. There are given its possible processing methods too. Next, there is desribed the mechanism of deposition of Ni-P coatings, components required to electroless deposition and factors affecting the quality and properties of these coatings. The theoretical part is ended by serie of reviews. Authors of these reviews deal with pretreatment of substrates, preparation, characterization and measuring of mechanical, structure and corrosion properties of deposited coatings. The optimalization of pretreatment, parametres and composition of nickel bath suitable for magnesium alloys is described in experimental part. The microstructure, present interlayer between substrate and Ni-P coating and chemical composition of deposited coatings was observed and measured by optical and electron microscopy. The mechanical characterization of Ni-P coatings was performed by microhardness tester.

Surface treatments in mechanical engineering
Čudová, Monika ; Kubíček, Jaroslav (referee) ; Žák, Ladislav (advisor)
The project was developed within the bachelor study presents experimental verification of two given varnishes. They are applied on a specially made plate. It was based on literary studies of corrosion coatings issues - coatings and practical tests. The samples were painted and tested according to the standards. The samples were tested on adhesion of varnishes, bending test and salt stray test. Finally all tests were evaluated.

Surface treatments of material
Tichý, Jan ; Kolář, Ladislav (referee) ; Fiala, Zdeněk (advisor)
This thesis deals with surface treatment materials, focusing on the process of plastic powder coating. The thesis describes several exclusive finishes that are entirely recommended as pre-treatment for powder coating. The thesis also provides information gained through market research, focusing specifically on powder plastics and technical equipment for powder coating. Technical equipment for the existing powder coating plant of the company KOVOT Invest Ltd. is also suggested.

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.
