Application of image analysis for cavitation erosion monitoring of some engineering materials
(Bor : University of Belgrade - Technical Faculty in Bor, 2023)
Engineering materials are often used in various operating conditions including high temperatures,
pressure, aggressive solutions, or cavitation erosion. The phenomenon of cavitation erosion is expected
when fluid flow ...
Cavitation erosion resistance of some engineering materials
(Association of Metallurgical Engineers of Serbia (AMES), 2023)
Cavitation erosion behavior of engineering materials is very important for various applications, such are
industrial/military/power station equipment and parts, such as pump impellers, delicately balanced high-speed ...
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 ...
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 ...
Assessment of Emissions into the Atmosphere from Biogas Cogeneration Plant in Serbia
(Serbian society of corrosion and materials protection (UISKoZaM) / Udruženje inženjera Srbije za koroziju i zaštitu materijala, 2023)
Biogas je gasna smeša koja nastaje tretmanom otpadnih tokova u procesu anaerobne digestije.
Proizvodnja električne energije iz kogeneracionih postrojenja koja koriste biogas je u porastu u
Republici Srbiji. U ovom radu ...
Quality of explosively welded steel plates using demex explosive
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS) - Društvo za procesnu tehniku, 2023)
Заваривање експлозивом се често користи када конвенционалне методе заваривања не
могу да обезбеде заварени спој два различита материјала, али и када треба заварити неку
специфичну геометрију или велике површине металних ...
