Effect of plasma hardfacing and carbides presence on the occurrence of cracks and microcracks
(Institut za ispitivanje materijala, Beograd, 2018)
Presented is the effect of plasma hardfacing (or just hardfacing) and carbides presence on the occurrence of cracks and microcracks in the welded layer. The reasons behind this phenomenon are analysed and explained. In ...
Influence of Friction Welding Parameters on Properties of the Al-Cu Joint
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
In this paper is presented a theoretical-experimental analysis of the aluminum-copper joining by friction welding. Considering that such Al-Cu bimetal joints are widely applied in industrial practice, experimental analysis ...
External atmospheric influences on the mechanical properties of resin-bonded grinding wheels with aluminium oxide and silicon carbide grains
(Institut za ispitivanje materijala, Beograd, 2020)
Ageing effects on resin-bonded grinding wheel properties are presented, including aluminium oxide and silicon carbide influence. Furthermore, humidity is examined as the most likely cause of significant downgrade in ...
Characterization of a coating 316l applied by plasma transferred arc
(Savez hemijskih inženjera, Beograd, 2018)
Parts of industrial machines and structures are often exposed to the action of aggressive environments, which in a short period of time can provoke the loss of their integrity. It is well known that for extending the service ...
The effect of cracks on stress state in crane wheel hard-surface under contact loading
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Shown in this paper are the results of microstructure testing of crane wheels, along with the repair welding procedure performed by hard-surfacing. Repair welding involved the application of a welded layer to the crane ...
Microstructure and fracture mode of unalloyed dual-phase austempered ductile iron
(Savez hemijskih inženjera, Beograd, 2022)
Dual-phase ADI material microstructure consists of different amounts and morphologies of ausferrite and free ferrite, obtained by subjecting ductile iron to specific heat treatment. Its strength is lower compared to ...
Developing thermal insulation cement based mortars with recycled aggregate in accordance with Net Zero principles
(Science of Sintering, 2024)
The performance of thermo insulation rendering mortars with alternations in ratios
of powdered cordierite and talc was examined. The goal was to confirm that recycled
kilnware cordierite can be reapplied in the mortar ...
