Metrological confirmation of the measuring instrument
Nezdařilíková, Martina ; Bumbálek, Leoš (referee) ; Koška, Petr (advisor)
The aim of thesis is to analyse terms, definitions and parameters for specify the surface structure focuse on the surface roughness. There are analyze requeriment of European Standarts EN ISO 9001 and EN ISO 10012. Thesis focused on quality management in measurement process and monitoring in the both standarts. The last part of thesis design the matrological confirmation of MarSurf PS1.

Ovlivnění adheze u protikorozních organických povlaků
Nováčková, Monika
This diploma thesis deals with the adhesion influence of anticorrosion coatings that are applied on the surface of a metallic material. The first part of the work focuses on corrosion, its division and commonly found types. The following part is aimed at protecting against such corrosion damage, including all types of anticorrosion protection. A very important part of this work is surface preparation before application of paints, which is discussed in the third part, where are described the individual methods of preparation. The fourth part deals with the anchorage profile defined and described in detail, and mentioned is also the closely related surface roughness. The subsequent anchorage profile assessment is performed by the comparison method, which consists of roughness sample ranges and follows the part defining the coating compounds, their classification, labelling as well as the colour scheme, up to their properties and methods of application on the material surface. One of the most important parts of the work is the experimental section focused on adhesion testing of the selected coatings in four types of anchorage profile using the pull-off test. The last part is an analysis of the application of knowledge about the coating system adhesion in the field of expert engineering and proficiency.

Olejové povrchové úpravy dřevěných podlah v exteriéru
Jarkovský, Petr
This Bachelor thesis addresses problems associated with the change of surface tex-ture, shade and gloss retention of outdoors wooden floors treated by oil based coating depending on the type of wood used as well as coating composition. The work is sup-ported by practical measurements on specimens obtained from three different wood varieties which were subjected to three different oil surface treatments. Prepared sam-ples were exposed to outdoors weather conditions for a period of 142 days. Continuous-ly during this time laboratory measurements were performed and their results subsequently evaluated.
