Anodizing of Aluminium and Its Alloys
Remešová, Michaela ; Julišová, Martina (referee) ; Čelko, Ladislav (advisor)
This thesis focuses on the hard anodic oxidation of aluminum and its alloys. As an experimental materials were used various aluminum materials, produced by cold forming and casting. The work contains information about chemical composition of the base materials, photographs of their microstructure, the results of surface roughness before and after anodic oxidation, photo anodized layer, measurements hardness oxide layers. For study were used methods light microscopy, scanning electron microscopy, surface profilometry and microhardness measurements.

Application reamers with cermet cutting edge
Toman, Martin ; Plíšek, Jiří (referee) ; Kouřil, Karel (advisor)
This thesis deals with the technology of reaming aimed mainly on cermet reamers. In the introduction of the thesis, the basic parameters of precision, dimension tolerance, geometrical tolerance and surface roughness are shown. Also, the technology of reaming, parameters, geometry and sorting of the reaming tools is analyzed in depth. The overview of the world producers of reaming tools is also shown as a supplement. In the final part, an example of production optimization by replacing a reamer with a better performing one is shown. Experimental part of this thesis has been made in the cooperation with HAM-FINAL company.

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.
