Nimonic 263 microstructure and surface characterization after laser shock peening
(Croatian Metallurgical Soc, Zagreb, 2015)
The Laser Shock Peening (LSP) is applied to the surface of Nimonic 263 alloy. The changes in microstructure and surface topography are observed and analyzed by Scanning Electron Microscopy (SEM), profilometer and microhardness ...
The tribological performance of hardfaced/thermal sprayed coatings for increasing the wear resistance of ventilation mill working parts
(Univerzitet u Kragujevcu - Fakultet inženjerskih nauka, Kragujevac, 2015)
During the coal pulverizing, the working parts of the ventilation mill are being worn by the sand particles. For this reason, the working parts are usually protected with materials resistant to wear (hardfaced/thermal ...
Picosecond laser shock peening of base Nimonic 263 material and laser welded Nimonic 263 alloy / Mehanička obrada pikosekundnim laserom osnovnog materijala i zavarenih spojeva legure Nimonik 263
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2015)
Laser welding is a welding process with a high energy density and numerous advantages over conventional welding methods (narrow heat affected zone, lower heat input, less distortion, and the like.) Mechanical treatment ...
Examination of mechanical properties of acrilyc composite materials with different AL2O3 reinforcement by brazil test / Ispitivanje mehaničkih svojstava akrilatnih kompozitnih materijala sa različitim AL2O3 ojačanjima brazilskim testom
(Savez inženjera i tehničara Srbije, Beograd, 2019)
Composite materials based on UV-curing acrylates and various alumina-based reinforcements represent material that is suitable for the use in dentistry, but also in other areas. Composites were made using four different ...
The effect of CaO and MgO addition and cooling rate on stability of slag obtained after jarosite and neutral leaching residue treatment in the Waelz process
(Oficyna Wydawnicza Politechniki Wroclawskiej, Wroclaw, 2018)
Jarosite and neutral leaching residue (NLR) are the greatest environmental problems of hydrometallurgical zinc production due to their high quantity and hazardous content. Pyrometallurgical processes, such as the Waelz ...
Characterisation of biomedical titanium layers deposited by a vacuum plasma spray process
(Materiali in Tehnologije, 2021)
In this paper we will describe the process of the deposition of thick layers of VPS-Ti coating, which is used as a bonding layer for the upper porous Ti coatings on implant substrates. In order to deposit the powder, we ...
The advantages of using activated flux-cored wire compared to solid wire in the mag welding process from the aspect of metallurgical characteristics
(Croatian Metallurgical Soc, Zagreb, 2014)
This paper analyzes, from the metallurgical aspect, the quality of the new flux-cored wire intended for the MAG welding process in function of changes in shielding gas composition and changes in welding parameters. The ...
Mechanical and structural characteristics of atmospheric plasma-sprayed multifunctional tio2 coatings
(Materiali in Tehnologije, 2020)
Titanium dioxide (TiO2) is a multifunctional oxide that is an interesting material for many technological applications. This paper presents the mechanical properties and microstructure of TiO2 coatings resistant to dry ...
