Complete characterization and comparison of lacquer / Ni-P / AZ91 and lacquer / AZ91 systems
Šomanová, Pavlína ; Doskočil, Leoš (referee) ; Buchtík, Martin (advisor)
The aim of this bachelor thesis was to compare the influence of Ni-P coating and varnish on the corrosion properties and chemical – physical properties (adhesion) of the magnesium alloy AZ91. The theoretical part contains the information about the alloy AZ91 itself and its microstructure, following by discussion about Ni-P coating, its properties, the process of the electroless deposition and composition it the nickel bath. Next chapter focuses on information about varnishes, its function and the process of its application on the surface of the substrate. Theoretical part closes with the summary of current research in the field of Ni-P coatings applied on magnesium alloys. The experimental part focuses on analysis of the microstructure of AZ91 alloy. The microstructure of the Ni-P coating and of the system Mg alloy/Ni-P coating/varnish was 4 examined by scanning electron microscope (SEM) and inverted microscope. During the next phase was thickness and hardness measured and composition measured by EDS analysis. The factor of the heat treatment of the samples and its impact on the final microstructure, hardness and corrosion resistance was taken in account. Finally, several samples were modified with the layer of the varnish and its thickness and the influence on the corrosion resistance ware measured. Samples were tested with electromechanical impedance spectroscopy (EIS), the corossion resistance were tested by neutral salt spray (NSS) and adhesive test was performed. The results showed, that Ni-P coating and the layer of varnish had positive impact on the corrosion resistance and the hardness of AZ91. The corrosion resistance of the samples modified with heat treatment was much lower, because of the contracting, which causes creation of the cracks. Also, the layer of varnish had positive effect on anticorrosion properties of tested AZ91 alloy.

Stanovení emisí těkavých organických látek z materiálů používaných pro výrobu nábytku
Šenkyříková, Tereza
The diploma thesis deals with the VOC substances and their impact on the indoor environment, health of human and environment. The work deals with the assessment of the emissions volatile organic compounds emit from materials used for the production of furniture in dependence on time. Focuses primarily on the most used construction material for production of furniture from particle board. The work assesses emitted substances from chosen glues/coating substances used for veneering/surface finishing of element.

Influence of kind of wood for quality of selected paints for exterior
Blažek, Tomáš ; Pánek, Miloš (advisor) ; Zeidler, Aleš (referee)
The aim of the diploma thesis is to provide lay persons as well as specialists in the field with information about a suitable surface treatment method for various types of wood and about the impact of the choice of wood on the coating durability when used outdoors, so that they make a sound judgement upon these findings. The diploma theses is divided into several parts containing an introduction into the problem of degradation of wood used outdoors, a description of various coatings based on natural substances, various wood modifications, principles of applying the coatings, norms providing for applying the coatings. On the basis of the tests using accelerated aging it has been found that the best results had oak with chemical modification Lignofix I-profi and final surface finish with the application of outdoor oil. The aim of the thesis is to compare selected coatings based on natural substances on selected types of modified wood. Outputs of particular tests are clearly arranged to provide a clear overview of particular measurement data. The diploma thesis also includes a clear analysis of particular coating materials with respect to their acquisition costs compared to their degradation and their utility.

Determining the resistance of paint films due to the thickness and number of layers
Ježek, Jan ; Bomba, Jan (advisor) ; Pánek, Miloš (referee)
In the theoretical part of this work there is described the theory of coating substances: sorts of coating substances, making a coating (paint) film and requirements of coating matters. In the practical part there was being found an affect of cold liquids upon concrete coating substances, an affect of the thickness of the coating film upon the resulting surface resistence and an affect of wood upon the quality of the coating. No difference of film quality of coating substances applied to conifers and leafy wood was evidenced. The quality of coating was applied to plawood materials where pores of the upper veneer were filled with paste and so there was no difference between conifers and leafy wood. According to statistics there is no important affect upon the film quality. The coatings 80 and 150g/m2 were used, which are the limited statements of an interval recommmended by producers and the quality of coating is declared. The result: the most aggressive liquid was remover, then plum brandy, Savo liquid, vinegar and mouthwash. Jar, the preparation for washing dishes, was the least aggressive.
