Electric probe measurements in the anode area of a DC arc plasma torch at low pressure
Ondáč, Peter; Mašláni, Alan; Hrabovský, Milan
2018 - English
We measured radial profiles of the electric field, plasma electrical potential and electron temperature in the hot anode area of a hybrid water-argon DC arc plasma torch with an external anode. The measurements were made under different values of the ambient pressure, during the restrike mode with a constricted anode arc attachment or during a supersonic mode with a diffuse anode arc attachment. The results provide first experimental data on plasma electrical potential in that anode area.

The Telescopes of Dall-Kirkham
Rail, Zdeněk; Ulrichová, Iva; Kuryshev, V.; Vápenka, David
2018 - Czech
The paper deals with the optical aberrations of the two-mirror telescopes composed of the ellipsoidal primary and the spherical secondary mirrors. The system was discovered by Horace Dall and Alan Kirkham at the end of the Twenties of the 20th Century. Its optical elements are easy to manufacture and measure. These telescopes can be equipped by lens correctors and turned into multipurpose devices both for planetary observation and wide field photography. Several telescopes were manufactured in workshop of the Toptec Center in Turnov. Referát se zabývá optickými vadami dvojzrcadlových dalekohledů s elipsoidálními primárními a sférickými sekundárními zrcadly. Systém byl objeven na konci dvacátých let minulého století Horacem Dallem a Alanem Kirkhamem. Jeho optické prvky jsou snadno vyrobitelné a měřitelné. Tyto dalekohledy lze vybavit korektory a vytvořit z nich víceúčelové přístroje jak pro planetární pozorování, tak pro fotografování širokých zorných polí. Několik takových přístrojů bylo vyrobeno i v dílně Centra Toptec v Turnově.

The effect of spark plasma sintering on the porosity and mechanical properties of Ti-15Mo alloy
Terynková, A.; Kozlík, J.; Bartha, K.; Chráska, Tomáš; Dlabáček, Zdeněk; Stráský, J.
2018 - English
Metastable β-titanium alloys are receiving much interest for various applications such as aircraft industry and medicine thanks to their excellent mechanical properties and biocompatibility. The common way of preparing the titanium alloys is hindered by its production costs. Powder metallurgy (PM) approach is a promising route for cost-effective fabrication of titanium alloys due to possibility of near net shaping. In this study, binary biomedical Ti-15Mo alloy was prepared by PM. Gas atomized powder was sintered by spark plasma sintering (SPS) above the β-transus temperature of the studied alloy. The compaction of the powders was accomplished by short-time sintering. The effect of the time of sintering on the porosity and the microhardness in centre part as well as in periphery part of the sample was investigated. The samples revealed significant inhomogeneity the porosity increases with the distance from the centre of the specimen. With increasing sintering times the porosity decreases and simultaneously the microhardness increases.
