Exploitation properties of ni-pd/al2o3 catalyst supported on ceramic foam
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The goal of this research was to examine exploitation properties of Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam in the dry methane reforming. The catalyst was prepared by using aerosol method. Chloride precursors ...
Anodization of Ti-based materials for biomedical applications: A review
(Association of Metallurgical Engineers of Serbia, 2016)
Commercially pure titanium (cpTi) and titanium alloys are the most commonly used metallic biomaterials. Biomedical requirements for the successful usage of metallic implant materials include their high mechanical strength, ...
Analysis of metal ion release from biomedical implants
(Association of Metallurgical Engineers of Serbia, 2013)
Metallic biomaterials are commonly used for fixation or replacement of damaged bones in the human body due to their good combination of mechanical properties. The disadvantage of metals as implant materials is their ...
Complex sulphide-barite ore leaching in ferric chloride solution
(Association of Metallurgical Engineers of Serbia, 2016)
The results of research on the leaching process of complex sulphide-barite ore were presented in this paper. The leaching process was carried out in a laboratory autoclave by ferric chloride solution. Considering that those ...
Influence of the fabrication process of copper matrix composites on cavitation erosion resistance
(Savez inženjera metalurgije Srbije, Beograd, 2017)
Copper matrix composites reinforced with ZrB2 particles were produced in two ways: by hot pressing (HP) and laser-sintering process. Powder mixture Cu-Zr-B was mechanically alloyed before densification processes. Variations ...
Thermal and mechanical properties of high alumina low cement castable
(Association of Metallurgical Engineers of Serbia, 2012)
Alumina based low cement castable (LCC) was synthesized and then treated from room temperature to 1600°C. Ultrasonic measurements were applied with the aim to obtain results of longitudinal and transversal ultrasonic ...
The morphology of ductile cast iron surface damaged by cavitation
(Association of Metallurgical Engineers of Serbia, 2012)
The study was designed to investigate the cavitation behavior of the ductile cast iron with microstructure consisting of spheroidal graphite in a predominantly ferrite matrix with 10% pearlite. The experiments were conducted ...
Conceptual design for treatment of mining and metallurgical wastewaters which contains arsenic and antimony
(Association of Metallurgical Engineers of Serbia, 2012)
This paper presents a preliminary design for treatment of mining and metallurgical wastewaters (MMW) from the basin of antimony 'Zajača', which contains high concentrations of arsenic and antimony. MMW have been investigated ...
Analysis of copper losses throughout weak acid effluent flows generated during off-gas treatment in the new copper smelter RTB Bor
(Association of Metallurgical Engineers of Serbia, 2013)
The previous inadequate treatment of off-gas in RTB Bor in Serbia has resulted in serious pollution of the environment and the possibly high losses of copper through the effluent flows. The project of New Copper Smelter ...
The inhibitive effect of ethanolamine on corrosion behavior of aluminium in NaCl solution saturated with CO2
(Association of Metallurgical Engineers of Serbia, 2012)
In this study, the inhibitive effect of ethanolamine on corrosion behavior of aluminium was investigated in 3 wt. % NaCl solution, saturated with CO2. All the experiments were carried out at 20°C. Ethanolamine was added ...
