Feasibility Analysis for Repair of Large Diameter Hydro Turbine Shaft Based on Weldability Test and Welding Cycle Simulation
(Advanced Materials Research, 2019)
Turbine and generator rotors and shafts undergo high stresses during regular working lifeand, from a safety and operational aspect, are the most significant components of a powergeneration system. Depending on the appropriate ...
Cavitation damage morphology of glass-ceramics based on basalt
(Serbian Ceramic Society Conference ADVANCED CERAMICS AND APPLICATION VIII New Frontiers in Multifunctional Material Science and Processing, Serbia, Belgrade, 23-25.09.2019, The Book of abstracts, 2019)
Cavitation is a kind of wear and represents formation, growth and collaps of steam or vapor gas bubbles in a flowing fluid. Collapse of the bubble creates shock waves and micro–jet that are damaging materials in contact ...
Kontrola kvaliteta vatrostalnih premaza primenom ultrazvučne vibracione metode sa stacionarnim uzorkom
(11 Naučno-stručni skup sa međunarodnim učešćem ”QUALITY 2019“, Neum, B&H, 14-16 juni 2019., 2019)
U istraživanjima je primenjena ultrazvučna vibraciona metoda za ispitivanje kvaliteta zaštitnih
vatrostalnih premaza na bazi bazalta. Određena je otpornost slojeva premaza na dejstvo kavitacije.
Detaljnom analizom promena ...
Influence of Mechanical Activation of a Cordierite –Based Filler on Sedimentation Stability of Lost Foam Refractory Coatings
(Science of Sintering, 2019)
For the development of the Lost Foam refractory coatings with controlled rheologic properties, the influence of the mechanical activation process on the cordierite-based filler's properties change was examined. First of ...
Application of glass- ceramic based on basalt for the production of parts of equipment in metallurgy
(14th International Conference on Accomplishments in Mechanical and Industrial Engineering, DEMI 2019, Proceedings, 2019)
The paper examines the cavitation resistance of glass-ceramics samples based on basalt from the Vrelo Kopaonik deposit. The experiment was conducted using an ultrasonic vibration method (with the stationary sample) according ...
Synthesis and characterization of new refractory coating based on basalt
(4th Metallurgical & Materials Engineering Congress of South-East Europe(MME SEE 2019) Belgrade, Serbia, 2019)
Basalt is a hard volcanic rock. Good technical properties make basalt an

Mikronizirajuće mlevenje pirofilita- Parsović- Konjic (BiH)
(Rudarstvo 2019 10. Simpozijum sa međunarodnim učešćem, Bor, 28-31 maj 2019, Zbornik radova, 2019)
Mikronizacija pirofilita je veliki tehnološko-tehnički problem, iz razloga što klasične mašine za usitnjavanje ne mogu svojim procesnim uslovima da ga mikroniziraju do finog i posebno veoma finog granulometrijskog sastava, ...
Comparison of the formation and development of cavitation damage on cast and sintered samples based on basalt
(Journal of Mining and Metallurgy, Section A: Mining, 2019)
The paper examines the resistance to the effect of cavitation of glass-ceramics based on basalt. Two types of samples were investigated: cast and sintered samples based on basalt.The cavitation erosion test was performed ...
The influence of grooves on the behavior of steel tube shock absorbers
