AB  - Even though it has been in use for a very long time, the high chromium white cast iron (HCWCI) still triggers scientists  due to its outstanding wear resistance. Besides its well-known as-cast usage, it can be used as a coating material, as well.  HCWCI owes this feature due to the presence of carbides in microstructure, which depends on the composition and heat  treatment regime. This investigation was conducted on two HCWCI alloys, where in addition to chromium, the second  important alloying element is molybdenum (Mo). Apart from other alloying elements, HCWCI_1 is alloyed with 24.48%  Cr and 1.32% Mo, while HCWCI_2 contains 14.11% Cr and 2.47% Mo. The comprehensive microstructural  characterization was carried out on as-cast samples and samples obtained after quenching (at -196oC) and/or quenching  followed by tempering (at 250oC). Important microstructure indicators are: the stability of austenite, the ratio of microconstituents (especially different types of carbides), as well as their arrangement and morphology, so they are revealed  and discussed in relation to the influencing mechanical properties.

AB  - Microstructure assessment is crucial for the design and production of high-quality alloys such as cast aluminum alloy ingots. Along with the effect of a more homogeneous microstructure to result in much better mechanical properties, better as-cast alloy quality indicates a higher efficiency of the aluminum alloys production process. During the aluminum alloy solidification process many microstructural defects can occur, which deteriorate the mechanical properties and hence decrease the usability of such an ingot. Application of the electromagnetic field during the vertical continuous casting process significantly reduces occurrence of these defects. In the present study, EN AW 7075 alloy samples were cast with and without application of an electromagnetic field and examined regarding the microstructure, electrical conductivity, and changes in the phase composition. The obtained results clearly show that it is possible to decrease or avoid casting defects by the electromagnetic field application as verified by the microstructure characterization and quantification, electrical conductivity tests and differential thermal analysis (DTA).
AB  - Određivanje i analiza mikrostrukture su presudni tokom dizajniranja i prilikom dobijanja legura aluminijuma visokog kvaliteta u livenom stanju. Pored neizbežne povezanosti homogenije mikrostrukture i boljih mehaničkih svojstava, bolji kvalitet u livenom stanju ukazuje i na veću efikasnost procesa proizvodnje legura aluminijuma. Tokom procesa očvršćavanja legure aluminijuma mogu se pojaviti mnogi mikro-strukturni nedostaci koji pogoršavaju mehanička svojstva, a samim tim i upotrebljivost takvog odlivka. Delovanje elektromagnetnog polja tokom procesa vertikalnog kontinualnog livenja značajno smanjuje pojavu ovih grešaka. Ovde prikazani rezultati dobijeni ispitivanjem mikrostrukture, električne provodljivosti i promene faznog sastava uzoraka legure EN AV 7075, odlivene u prisustvu elektromagnetnog polja, kao i bez njega, jasno pokazuju da je moguće smanjiti ili izbeći nedostatke livenja pri-menom elektromagnetnog polja. To je pokazano pomoću određivanja i analize mikro-strukture, ispitivanja električne provodljivosti i diferencijalne termičke analize (DTA).

AB  - Magnetic thin films based on iron group elements (Fe, Co, Ni) are currently used in computer's hard disk drives and in MEMS, whereas electrodeposition is a suitable method to obtain these materials. The powders of metals and alloys were obtained by electrochemical deposition at constant current density using alkaline ammonium electrolyte which consist one, two or three different elements Co, Ni and Mo. Ni and Co are deposited anomalously. The Mo element cannot be obtained electrochemically from the aqueous solutions. Electrochemical deposition of this metal is induced by codeposited iron-group metals, Ni and Co, for instance. This study investigates the influence of electrochemical parameters on composition and properties of obtained powders. Based on the obtained experimental results, it could be concluded that the particle size of deposited powders and chemical composition are influenced by the chemical composition of the electrolyte, with changing the concentration ratio of ions of metallic salts as well as current density imposed. As a consequence, the changes in magnetic properties are obvious. The structure and morphology of powders were investigated by Scanning Electron Microscopy (SEM). For demonstration of mechanism of powder deposition Image ProPlus software for SEM microphotograph analysis was used. The values of individual objects as well as formed clusters of powders were measured by this technique. The chemical composition of the powders was determinate using Energy Dispersive X-ray (EDX) analysis. XRD results suggested that obtained powders were of amorphous structure.

AB  - The Co-Ni-MoxOy powders were obtained electrochemically at a constant current density from ammonia electrolyte. Ni and Co were anomalously deposited, inducing Mo deposition, which cannot be deposited separately from aqueous solutions. The obtained Co-Ni-MoxOy powders were investigated by energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and scanning electon microscope (SEM) methods. Based on the obtained experimental results, it was concluded that the particle size of deposited powders is influenced by the chemical composition of the electrolyte and current density imposed. XRD results suggested that obtained powders were of amorphous structure, although a Co3Mo compound can be formed if certain experimental conditions are applied.

AB  - This paper addresses on investigation the possibility of electrolytic treatment the sulphur acidic waste solution, obtained in the conventional electrolytic copper refining process. Beside the high copper concentration, the high concentration of other metals, in this case nickel, is the main characteristic of these waste solutions. Due to this fact, the copper bearing anodes with non-standard nickel, lead, tin and antimony content were specially prepared for the refining process. Nickel content of all anodes was approximately 7.5 mass%, and the content of lead, tin and antimony was varied. The preliminary results, obtained using the standard electrochemical techniques, have indicated that the copper bearing anodes could be used under the same conditions as well as in the conventional copper refining process. The measurements in constant galvanostatic pulse have pointed out that the all chemical elements from copper bearing anodes were dissolved and only copper was deposited onto the cathode. It was also pointed out that Ni concentration in the base working electrolyte (sulphur acidic waste solution), after 72 h of process, increased to 102 mass% at T-1 = 63 +/- 2 degrees C and up to 122 mass% at T-1 = 73 +/- 2 degrees C, while arsenic concentration decreased to a minimum value.
