The effect of cooling rate of slag from primary copper production in the valorization of copper in the flotation process
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Technological procedure of slow cooling slag from primary copper production is applied in the purpose of copper recovery in the level of 98.5% to blister. This technological procedure is divided into two phases, first slow ...
Investigation of copper(i) sulphide leaching in oxidative hydrochloric acid solution
(Savez inženjera metalurgije Srbije, Beograd, 2015)
Present work is focused on the copper (I) sulphide leaching with sodium chloride in hydrochloric acid solution and with introduction of gaseous oxygen. Chemical reactions of leaching and their thermodynamic probabilities ...
Indentation behaviour of 'soft film on hard substrate' composite system type / Ponašanje kompozitnih sistema tipa 'mek film na tvrdom supstratu' na testu utiskivanja
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
This investigation has been carried out in order to analyse and compare the hardness response of different composite systems of the same type, named 'soft film on hard substrate' composite system. Composite systems of mono- ...
Synthesis of high-performance alkyd anticorrosion coatings based on waste poly(ethylene terephthalate) / Sinteza visokoefikasnih alkidnih antikorozionih premaza na bazi poli(etilen tereftalata)
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
Synthesis of high-performance anticorrosive coatings obtained from alkyd resins (ARs) based on waste poly(ethylene terephthalate) (PET) glycolyzates is presented. PET glycolyzates, synthesized by catalytic depolymerization ...
Ni-pd/al(2)o(3) catalyst supported on reticulated ceramic foam for dry methane reforming
(Savez inženjera metalurgije Srbije, Beograd, 2015)
In the present study, Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam was prepared and evaluated in the dry methane reforming process. Corresponding metal chlorides were deposited to the foam surface by impregnation ...
Numerical simulation of temperature field in the vertical bridgman method crystal growth
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The mathematical model for heat transfer during the Bridgeman crystal growth, using the finite element method and the obtained result are presented. Some modifications to the method were introduced in order to incorporate ...
Studying of physicochemical properties of newly synthesized uracil derivatives / Proučavanje fizičko-hemijskih svojstava novosintetisanih derivata uracila
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
Uracil derivatives are potentially biologically active compounds, so the investigation of their physical and chemical properties is very important for their further application. In this work a series of newly synthesized ...
Impact of roughness of Zn-Mn coatings on corrosive stability / Uticaj hrapavosti Zn-Mn prevlaka na korozionu postojanost
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
This paper involves electrochemical deposition of Zn-Mn coatings from four solutions. We measured their roughness and corrosion stability. We used cathodes made of steel of unknown composition that were licensed under the ...
Finite element analysis of fracture resistance parameters for stationary semi-elliptical surface cracks in high strength steel / Analiza parametara otpornosti na lom metodom konačnih elemenata, kod stacionarnih polueliptičnih prslina u čeliku povišene čvrstoće
(Society for Structural Integrity and Life, Institute for Material Testing, 2015)
This study deals with numerical simulations based on elastic-plastic finite element method for nonlinear stress analyses on pre-cracked tensile specimens with high strength properties. The influence of crack geometry on ...
Application of exergy analysis in recycling streams / Primena eksergijske analize u reciklažnim tokovima
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
Materials for recycling always contain a certain degree of contamination. The presence of impurities i.e. contamination in the recycling streams causes a change in the composition of the original materials to recycle. As ...
