Cavitation Wear of Basalt-Based Glass Ceramic
(MDPI, Basel, 2019)
This paper examines the possibility of using basalt-based glass ceramics for construction of structural parts of equipment in metallurgy and mining. An ultrasonic vibration method with a stationary sample pursuant to the ...
Nastajanje i razvoj oštećenja bazalta pod dejstvom kavitacije / Formation and development of damage of basalt under the effect of cavitation
(Inženjersko društvo za koroziju, Beograd, 2019)
U radu je ispitivana otpornost na dejstvo kavitacije uzoraka livenog bazalta. Uzorci su dobijeni topljenjem, livenjem i termičkim tretmanom izdrobljenih bazaltnih stena iz ležišta Vrelo Kopaonik. Eksperiment je vođen ...
The Mechanisms of Cavitation Erosion of Raw and Sintered Basalt
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
The paper analyzes the morphology of cavitation damage of raw and sintered basalt samples. The experiment was conducted using the ultrasonic vibratory cavitation test method according to the ASTM G-32 standard. During the ...
Cavitation resistance of composite polyester resin/basalt powder
(Institut za ispitivanje materijala, Beograd, 2019)
The paper presents the results of research on cavitation resistance of the composite based on unsaturated polyester resin and basalt powder, as reinforcement. Basalt powder was obtained by grinding and micronising basaltic ...
On biomimetics in machine elements design
(Manipal University Jaipur, India, 2019)
The aim of the paper is to point up the possibilities of biomimetics principles in the machine elements design. During last decades, the new requirements in machine elements design are placed in front of the experts. The ...
Great persons and results make biomimetics incredibly inspirational
(Abstracts of 15th International conference Dynamical Systems - Theory and Applications, 2019)
The concept of using ideas from nature as inspiration for innovation and technological development is in focus last decades, while the similar approach can be found in the ancient civilizations. In any kind of such progress ...
Determination of cavitation resistance of sintered basalt samples
(51st International October Conference on Mining and Metallurgy, 16-19 October 2019, Bor Lake, Proceedings, 2019)
The paper examines the cavitation resistance of the sintered basalt samples. A change in the sample mass in function of the cavitation time was monitored for the evaluation of cavitation resistance. The level of degradation ...
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 ...
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 ...
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 ...
