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 ...
Effects of application on new casting methods on quality of casting and productivity of copper alloy castings
(3rd International Symposium of Natural ResourcesManagement, Zaječar 30-31 May 2013, Proceedings,, 2013)
In this paper, results of investigation of new methods of casting of copper alloys with accent on the Lost foam process are presented. Phases of casting procedure were investigated, along with important process parameters ...
Defects in casting caused by hyman error
(3rd International Symposium of Natural Resources Management, Zaječar 30-31 May 2013, Proceedings, 2013)
This paper analysed the influence of various factors on moulding discontinuities and moulding quality. The research established that most causes were rooted in a casting process itself, such as: the method of alloy ...
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 ...
Characterization and determination of erosion resistance of refractory materials for application in metallurgy and minnig
(VI International Congress “Engineering, Environment and Materials in Processing Industry“, Jahorina 2019, 2019)
The paper presents the results of the investigation of the cavitation resistance of refractory materials based on basalt, mullite, cordierite, zircon and chromite for the production of parts of equipment in metallurgy and ...
