Management of environmental quality and Kostolac mine areas natural resources usage
(Management of Environmental Quality: An International Journal, 2014)
Purpose – This paper aims to define and theoretically analyse the performance of modern
methods investigated to speed up the recultivation process of degraded areas, and apply it into
the mining basin, open pit mines, ...
Cavitation damage of mullite ceramic: Implementation of image analysis
(48th International October Conference on Mining and Metallurgy, Bor 2016, Proceedings, 2016)
The paper presents the results of testing the mullite ceramics in terms of cavitation erosion. Mullite samples were sintered at 1200ºC. To determine the cavitation resistance the ultrasonic vibration method with stationary ...
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 ...
Calcium Carbonate Fillers Prepared by Means of Micronized Milling with Application in Coatings
(The Serbian Ceramic Society Conference Advanced Ceramics and Applications III: New Frontiers in Multifunctional Material Science and Processing, Belgrade, 29th September - 1st. October, 2014, 2014)
Rapid technological development in past few decades led to formation of a certain group of ceramic materials which are often referred to as “coating agents”. This term is rather descriptive because materials that belong ...
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 ...
Determination of Degradation Level during Cavitation Erosion of Zircon Based Ceramic
(Science of Sintering, 2017)
Mechanical shock of zircon based ceramic induced by cavitation erosion testing was investigated in this study. Several parameters were followed in order to determine level of material degradation during the cavitation ...
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 ...
Application of Chromite in the Production of Refractory Coatings
(InterCeram: International Ceramic Review, 2013)
This work investigated the possibility of developing new chromite-based refractory coatings for hot metal casting applications. The coating composition and rheological properties were optimized by careful choice of binding ...
A theoretical model for vibro-impact dynamics of spur gears with tooth flanks wear
(NODYS Publications, Rome, Italy, 2019)
The main performances of involute gears operations lead to the appearance of nonlinear dynamic behaviour and impact. In this paper the influence of mild wear of the tooth flanks of gears without surface hardening on the ...
