Multicomponent Thin Films Deposited by PVD ARC and LARC Technology

Autor: Dagmar JAKUBÉCZYOVÁ, Marek KOČÍK, Pavol HVIZDOŠ

Publikováno v: Medžiagotyra, Vol 20, Iss 1, Pp 36-41 (2014)

The paper is focused on a comparison of advanced layers deposited by two coating technologies – cathodic arc deposition (ARC) and lateral rotating cathodes (LARC). For characterization standard analyses were selected: the determination of the layer

PPHASE AND MORPHOLOGY FORMATION OF Na DOPED PMN THIN FILMS PREPARED BY MODIFIED SOL-GEL METHOD

Autor: HELENA BRUNCKOVÁ, ĽUBOMÍR MEDVECKÝ, JURAJ ĎURIŠIN, PAVOL HVIZDOŠ

Publikováno v: Ceramics-Silikáty, Vol 57, Iss 1, Pp 22-27 (2013)

Na doped lead magnesium niobate Pb(Mg1/3Nb2/3)O3 (Na-PMN) thin films of 100 nm thickness were prepared by modified sol-gel route with niobium precursor. Na-PMN films were deposited from sol derived using tartaric acid modified polymerizable complex m

Flash Spark Plasma Sintering of SiC: Impact of Additives

Autor: Salvatore Grasso, Sandan Kumar Sharma, Michael J. Reece, Martin Fides, Pavol Hvizdoš

Publikováno v: Silicon. 14:7377-7382

Flash spark plasma sintering (FSPS) of SiC was carried out using additives (10 vol%) with different electrical conductivities: alumina (insulator), boron carbide (semiconductor), and titanium carbide metallic (conductor). The electrical conductivity

Effect of ZrC nanopowder addition in WC preforms on microstructure and properties of W–ZrC composites prepared by the displacive compensation of porosity (DCP) method

Autor: Pavol Hvizdoš, Dusan Galusek, Fathallah Qods, Aliasghar Najafzadehkhoee, Ali Habibolahzadeh, Maryam Vakhshouri, Wojciech Polkowski

Publikováno v: Journal of the Australian Ceramic Society. 57:515-523

In the present work, WC preforms with varied amounts of ZrC nanopowder (0–3.5 vol.%) were prepared using gel-casting base on nontoxic sodium alginate and then reactively infiltrated by molten Zr2Cu through displacive compensation of porosity method
