Aramid composites impregnated with different reinforcement: Nanofibers, nanoparticles and nanotubes / Aramidni kompoziti impregnisani sa različitim ojačanjima - nanovlakna, nanočestice i nanocevi
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
In this study, the electrospun nanofibers, nanoparticles and nanotubes were used as reinforcement in order to improve mechanical properties of materials for ballistic protection. The samples of polyurethane/p-aramid ...
Simulation of velocity profile inside turbulent boundary layer
(Association of Metallurgical Engineers of Serbia, 2020)
The second-order differential equation with a general polynomial solution [1], is adapted for simulation of complex velocity profile inside the turbulent boundary layer. Consequently, the simulation strategy is suggested.
Oxidation and erosion behaviour of SiC-HfC multilayered composite
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2014)
The fabrication of SiC-HfC ceramic composite via self-propagating high-temperature synthesis and simultaneous consolidation was investigated. Dense composite consisting of alternating layers of SiC and HfC was obtained by ...
Impact of roughness of Zn-Mn coatings on corrosive stability / Uticaj hrapavosti Zn-Mn prevlaka na korozionu postojanost
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
This paper involves electrochemical deposition of Zn-Mn coatings from four solutions. We measured their roughness and corrosion stability. We used cathodes made of steel of unknown composition that were licensed under the ...
The effect of mould temperature and cooling conditions on the size of secondary dendrite arm spacing in Al-7Si-3Cu alloy
(Savez inženjera metalurgije Srbije, Beograd, 2009)
The secondary dendrite arm spacing (SDAS) is one of the most important microstructure features of as-cast structure in hypoeutectic aluminum alloys. The size of SDAS depends on many factors such as liquid metal treatment, ...
Hydrometallurgical process for extraction of metals from electronic waste, Part I: Material characterization and process option selection
(Savez inženjera metalurgije Srbije, Beograd, 2009)
Used electronic equipment became one of the fastest growing waste streams in the world. In the past two decades recycling of printed circuit boards (PCBs) has been based on pyrometallurgy, highly polluting recycling ...
Chemical durability of sintered glass-composite prepared from glass cullet and waste foundry sand
(Metallurgical & Materials Engineering, 2021)
In this study, the glass-composite was prepared using glass cullet and waste foundry sand as raw materials. The powder technology route was employed. The mixtures containing 10-50 wt% of the sand were sintered at T = 750 ...
Nanostructured intrinsically conducting polymers formed by electrochemical synthesis / Nanostruktuirani elektroprovodni polimeri dobijeni elektrohemijskom sintezom
(Engineering Society for Corrosion, Belgrade, Serbia, 2016)
Due to unique properties of intrinsically conducting polymers (ICP) such as: electrical conductivity, reversible electrochemistry, optical activity, biocompatibility, environmental and corrosion stability, they still ...
