Termodinamična karakterizacija Al zlitine Silafont-36
Karlo Rudolf, Maja Vončina
Diplomsko delo
Oznake: zlitina Silafont-36;dodatek Zr in/ali Mo;enostavna termična analiza;diferenčna vrstična kalorimetrija;termodinamični izračun faznih ravnotežij;
Med kovinami je aluminij eden od najpogostejših materialov, ki ga uporabljamo v različnih aplikacijah. Za doseganje željenih lastnosti materiala na osnovi aluminija, dodajamo določene legirne elemente, kot so Cu, Mg, Si, Mn, Zn, Fe itd. Silicij izboljša livnost, poveča odpornost proti obrabi. Mang ...

Vpliv specifične površine in deleža sekundarnega aluminija na kakovost zlitine AlSi10Mg(Fe)
Karlo Rudolf, Maja Vončina
Magistrsko delo
Oznake: zlitina AlSi10Mg(Fe);reciklaža;termodinamika;mehanske lastnosti;mikrostruktura;strjevanje;
Aluminij je ena od barvnih lahkih kovin. Zaradi dobrih mehanskih lastnosti je druga najbolj uporabljena kovina. Aluminijevo livarska zlitina AlSi10Mg je pogosto uporabljena v avtomobilski industriji, predvsem zaradi ohranjanja dobrih mehanskih lastnosti pri povišanih obratovalnih temperaturah. V liv ...

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 ...

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 ...
