Energy efficient pulse-reverse regimes of electrodeposition / Energetski efikasni pulsno-reverzni režimi galvanizacije
(Union of Mechanical and Electrical Engineers and Technicains of Serbia (SMEITS)Society for Renewable Electrical Power Sources, 2017)
Pulse reverse power modes are used in order to obtain metal coatings with similar or better characteristics, compared with the coatings produced by constant current. Pulse reverse modes increase production and energy ...
Damage level evaluation of zircon samples caused by cavitation erosion using image analysis
(Bor : University of Belgrade - Technical Faculty in Bor, 2017)
This study is focused on monitoring the degradation level of zircon based ceramic materials during exposure to cavitation. In addition to conventional degradation monitoring methods, weight loss measuring, the emphasis is ...
Cavitation damage of mullite ceramic: implementation of image analysis
(Bor : University of Belgrade - Technical Faculty in BorBor : Mining and Metallurgy Institute Bor, 2016)
The paper presents the results of testing the mullite ceramics in terms of cavitation erosion. Mullite samples were sintered at 1200 °C. To determine the cavitation resistance the ultrasonic vibration method with stationary ...
Valorization of secondary sulfur from oil refining process for sulfur concrete production
(Bor : University of Belgrade - Technical Faculty in Bor, 2015)
Modification of conventional building materials is commonly realized using different waste materials. In this research, the use of secondary sulfur as binding agent in concrete was analyzed. Sulfur concrete is a thermoplastic ...

In this paper, results of investigation of casting technology of complex thin-wall copper alloy castings with accent on Lost Foam casting procedure are given. Phases of casting procedure were investigated, along with ...
Leaching behavior of sulfur concrete with fly ash used for removal of heavy metals from wastewater
(Belgrade : Mining institute BelgradeAcademy of Engineering sciences of SerbiaUniversity of Belgrade, 2015)
When considering the materials that have become waste in a technological process, one way of their immobilization is for the production of certain new materials. The basic fact is to provide the environmentally acceptable ...
Environmental influence on service life expectancy of ceramic structures
(Политехпериодика/Politehperiodika, 2015)
During the service life, materials are exposed to environmental influences. The aim of this research is to analyze behavior of sulfur concrete compared to Portland cement concrete in acid environment. It has been shown ...
Concentration method for the mining wastewater-valorization of the copper
(The Regional Environmental Center for Central and Eastern Europe, 2013)
During the mining process of copper exploitation, a large amount of wastewater is generated. Not only do the copper ions contaminate the water but also represent a great loss for the copper production industry. Negative ...
Application of polymer materials for production of evaporative pattern and development of new casting process
(Bor, Srbija : Tehnički fakultet Bor, Institut za rudarstvo i metalurgiju, 2012)
In this paper, results of the investigation of the polymer materials for evaporate patterns and their application in the new casting method (EPC process) are presented. The basic characteristic of EPC process is that ...
Possibility of using diatomaceous earth from Kolubara and Vesje deposits for production of beer filter aids
(Belgrade : Mining Institute BelgradeAcademy of Engineering Sciences of SerbiaUniversity of Belgrade, 2015)
Diatomaceous earth is a non-metallic mineral raw material composed of skeletal remains of
single-cell water plants, known as diatomite. Owing to quite complex structure of skeletal diatomite
with numerous fine microscopic ...
