Phase analysis using Fourier transform profilometry
Mandát, Dušan; Rössler, T.; Hrabovský, Miroslav
2005 - Czech
The profilometry method used here is the Fourier-Transform Profilometry Method that was originally published by Takeda in 1982. The geometry of the experiment is very similar that used in Moiré Topography, but the advantage of this method is only one image of the projected grating is necessary to produce the resulting object´s fringes. Fourierovská topografie publikovaná v tomto příspěvku pracuje na principu výpočtu změny fáze mezi referenční a objektovou přímkou. Sestava experimentu je podobná moiré topografii. Citlivost Fourierovské profilometrie je vyšší než moiré.

Properties of TIO.sub.x./sub. films deposited at atmosphere pressure
Sedláková, L.; Hubička, Zdeněk; Churpita, Olexandr; Stranyánek, Martin; Čtvrtlík, Radim; Špatenka, P.
2005 - Czech
TiOx films were deposited on silica glass by RF discharge in atmosphere pressure at low substrate temperature. Some properties of the films were studied depending on annealing temperature after deposition. The thickness, nanohardness, crystallinity and speed of photocatalysis degradation were investigated. TIO.sub.x./sub. byli deponovány za použití RF bariérového pochodňového výboje, který pracuje za atmosférického tlaku a při nízké teplotě substrátu. Jako prekurzor byly použity páry Titanium (IV) isopropoxide Ti[OCH(CH..sub.3./sub.).sub.2./sub.].sub.4./sub. a jako substrát křemenné sklo.Depoziční podmínky při tvorbě vrstev byly u všech vzorků stejné. Byly zkoumány vlastnosti vrstev v závislosti na teplotě žíhání po depozici. U vrstev byla hodnocena tloušťka, anotvrdost, krystalinita vrstev metodou XRD difrakce a rychlost fotokatalytické degradace.

Study of hard and abrasion resistant films on surface of nickel moulds
Cerman, J.; Špatenka, P.; Stranyánek, Martin; Čtvrtlík, Radim
2005 - Czech
The paper is dealing with some possibilities of using hard and abrasion resistant films deposited by PVD technology on less noble materials. The films are tested by some experimental equipment developed by TU Liberec simulated real wear. Contact profilometer is used. Thickness and Berkovich nanohardness are determined. Práce pojednává o možnostech použití tvrdých a otěruvzdorných vrstev, deponovaných technologií PVD, na povrchu forem vytvořených z méně ušlechtilých materiálů. Zkoumané vrstvy jsou testovány na otěruvzdornost pomocí experimentálního zařízení, navrženého v TU Liberec, simulující podmínky opotřebení formy během reálného provozu. Velikost opotřebení je vyhodnocena pomocí kontaktního profilometru. U vrstev je dále určena tloušťka pomocí kalotestu a nanotvrdost - typ Berkovich.
