Possible design and performance mistakes of welds for resulting chemical threatment by pickling
Hendrych, Marek ; Kubíček, Jaroslav (referee) ; Sigmund, Marian (advisor)
The diploma thesis deals with the issue of surface treatment by pickling. In the research part the pickling technology is described in detail. The next chapters are focused on the TIG welding method and the weldability of austenitic stainless steels. In the experimental part an experiment is carried out focusing on the comparison of weight loss and surface quality depending on the pickling time. Part of the conclusion is the implementation of pWPS documentation for the specified component and a brief manual for customers of pickling plant.

Influences of pickling on coating bonding power
Staněk, Vít ; Žák, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
Works created within the engineering studies in collaboration with IDEAL-Trade service discusses the influence of pickling acids on steel material and on the same material with powder coated . Based on the literature study and consultations with employees of the company were designed each experiment, investigators removal and acid corrosion attack , another verify adhesiveness powder coatings for various periods of exposure pickled material. Experiments and tests were carried out in companies ECOS , ITS and faculty FSI.

Vliv barevného odstínu pigmentové povrchové úpravy na teplotu povrchu nábytkových dílců
Plodíková, Lucie
The bachelor thesis based on experimental measurements of previously prepared samples. The samples are made of beech plywood. They are finished by pickling with various pigments and exposed to daylight in exterior. The thesis investigates influence of colour shade of pigment surface finishing on wood furniture to the physic-mechanical properties of surface finishing but mainly to the temperature of finished surface. Other properties examined are hardness, adhesion, and colour shade, degree of damage and abrasion resistance. The result of thesis is evaluation and description of achievements with the contribution for practice and new findings.

Možnosti zvýšení kvality osiva za použití stimulačních látek při semenářských technologiích (moření, inkrustace)
Prášil, Václav
Bachelor thesis Options for improving the quality of seeds using stimulants in seed technology (seed treatment, incrustation) describes possibilities of increasing seed quality in general, especially the seed plants in the family Apiaceae, which has long and difficult germination. There are described various factors affecting the quality of seeds and ways to improve seed quality. In the practical part were evaluated two kinds of plants: parsley (Petroselinum Crispum (MILL.) NYM. ex A. W. HILL convar. radicosum (ALEF.) DANERT) and carrot (Daucus carota L. subsp. sativus (HOFFM.) SCHÜBL & MART.) grown on two locations in 3 variantions of seed treatment and also control variant. Roots were weighted for evaluate total yield, yield of roots for markets and percentage of market roots from total yield.

Svetlostálosť morených povrchových úprav
Machunková, Andrea
This bachelor thesis deals with the influence of artificial UV radiation on plywood samples made of chosen woods - oak (Quercus), alder (Almus) and ash (Fraxinus) and examines the influence of surface conditioning on light permanency of wood surface. Samples were stained by water-soluble and solvent stains and finished by water-soluble and solvent lacquers. Samples were examined by standardized tests in the laboratory. We have determined the influence of type of stains on the speed of drying times and hardness and roughness of the coatings and evaluated changes in color depending on the surface conditioning.
