Liquid metal/ceramic interfaces in dental practice and jewellery manufacturing
Karlo Raić, Rebeka Rudolf, Aleksandar Todorović, Dragoslav Stamenković, Ivan Anžel
Pregledni znanstveni članek
Oznake: metal-ceramic bonding;brazing;soldering;dentistry;jewellery;
Metal-ceramic fusing has been the essential step in obtaining materials that benefit from both ceramic and metal constituents, i.e. where the combined properties of metal and ceramic layers are desirable. When considering fusing methods, soldering and active metal brazing are the most effective. The ...

Relationship between the calculated oxygen activity and the sulfur partition ratio for CaO-Al2O3-SiO2-MgO slag during ladle refining
Zoran Slović, Karlo Raić, Ljubomir Nedeljković, Tatjana Volkov Husović
Strokovni članek
Oznake: sulfide capacity;sulfur partition ratio;oxygen activity;optical basicity;KTH model;
A slag-metal equilibrium study was carried out to investigate the effect of oxygen activity on the sulfur partition for CaO-Al[sub]{2}O[sub]3-SiO[sub]2- MgO slag. The sulfide capacity C[sub]s prediction models by Sosinsky-Sommerville based on the optical basicity [lambda] and the KTH model in terms ...

Reduction of ultra-fine tungsten powder with tungsten (VI)-oxide in a vertical tube reactor
Željko Kamberović, Dušica Filipović, Karlo Raić, Miloš Tasić, Zoran Anđić, Milorad Gavrilovski
Izvirni znanstveni članek
Oznake: volframov oksid;redukcija;volframov prah;
The reduction of WO3 with hydrogen in a vertical tube reactor is a new approach to the reduction of tungsten oxide compared to conventional procedures in a stationary layer. The advantage of this method is the intensive contact between the reducent and the oxide particles, a higher degree and a shor ...

Nanofoils for soldering and brazing in dental joining practice and jewellery manufacturing
Karlo Raić, Rebeka Rudolf, Borut Kosec, Ivan Anžel, Vojkan Lazić, Aleksandar Todorović
Izvirni znanstveni članek
Oznake: ceramic-metal bonding;low-temperature;nano-foils;plasma technology;dentistry;jewellery;
This paper describes the development of novel, reactive Al-Au nano-multilayered foils, their possible application in different fields and a discussion of the nano-foils' suitability for dental and jewellery applications. Moreover, this study includes the rapid joining of similar and dissimilar mater ...

Aspects of titanium-implant surface modification at the micro and nano levels
Iva Milinković, Rebeka Rudolf, Karlo Raić, Zoran Aleksić, Vojkan Lazić, Aleksandar Todorović, Dragoslav Stamenković
Izvirni znanstveni članek
Oznake: implantati;titanove zlitine;modifikacija površine;mikrostruktura;implantat;titan alloys;surface modification;microstructure;
The shape and chemical composition, as well as the macro- and microtopography, of an implant surface have been studied widely as the major factors that positively influence implant osseointegration. Titanium and titanium alloys have been used extensively over the past 20 years as biomedical material ...

CFD analysis of exothermic reactions in Al-Au nano multi-layered foils
Karlo Raić, Rebeka Rudolf, Primož Ternik, Zoran Žunič, Vojkan Lazić, Dragoslav Stamenković, Tatjana Tanasković, Ivan Anžel
Izvirni znanstveni članek
Oznake: Au-Al nano-foils;finite volume method;temperature transfer;concentration transfer;
This work presents the possibility of numerical modelling using Computational Fluid Dynamics (CFD) in the field of nano-foils. The governing equations were solved using a Finite Volume Methodology (FVM). The computational domain was discretized using a uniform Cartesian grid with the appropriate mes ...

Hydroxyapatite coatings on Cp-Titanium Grade-2 surfaces prepared with plasma spraying
Rebeka Rudolf, Dragoslav Stamenković, Zoran Aleksić, Monika Jenko, Igor Đorđević, Aleksandar Todorović, Vukoman Jokanović, Karlo Raić
Izvirni znanstveni članek
Oznake: Cp-Ti2 material;hydroxyapatite;plasma;characterization;
Thin hydroxyapatite coatings were produced on Cp-Titanium Grade-2 samples, with new high-voltage pulse-power equipment PJ-100 (Plasma Jet, Serbia) in order to get a more stable implant structure appropriate for further clinical applications. A comparative analysis of differently prepared surfaces of ...
