Metal-metal composites with Zn-Al alloy base and addition of Ti microparticles reinforced with ceramic nanoparticles
(Sofia : Technical University, 2018)
The zinc-aluminium casting alloy ZA-27 is well-established alloy and is frequently used material for plain bearing sleeves. It has good physical, mechanical and tribological properties. Its tribological properties can be ...
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 ...
Microstructure and mechanical properties of the Mo-NiCrBSi coating deposited by atmospheric plasma spraying
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2009)
Prah koji je korišćen u ovom istraživanju (Mo-NiCrBSi) je mešavina dva praha, praha Mo i praha 'samotekuće' legure NiCrBSi, u procentualnom odnosu 75/25%. Nanošenjem ove mešavine prahova dobijena je 'samotekuća' prevlaka ...
Influence of plasma transferred arc welding parameters on the obtained microstructure of 316L coating
(Structural Integrity and Life, 2023)
The paper describes the surfacing technology for coating of high-alloyed austenitic stainless steel 316L on the steel S235JR base material. Coatings were applied by plasma transferred arc welding process. The 5 samples ...
