AB  - In the current study the ternary Ga-Ge-Zn system was experimentally and analytically tested. The ternary system is chosen due to the importance of germanium-based alloys in the electronic industry and their special application as memory materials. There are no previous studies related to the Ga-Ge-Zn system up to this paper. Used experimental techniques were differential thermal analysis, scanning electron microscopy with energy dispersive spectrometry, x-ray powder diffraction, electrical conductivity and hardness tests. The experimentally obtained results were compared with the results of thermodynamic calculation of phase equilibria using the calculation of phase diagram (CALPHAD) method and literature data. Calculated phase diagrams were three vertical sections (Ga-GeZn, Ge-GaZn and Zn-GaGe), three isothermal sections (100, 200 and 300 degrees C) and liquidus projection with invariant reactions. Good agreements between calculated phase diagrams and experimental data have been obtained without introducing ternary thermodynamic parameters.

AB  - The ternary Ge-In-Zn system is chosen for the study due to the importance of germanium-based alloys in the industry of electronic devices and their special application as memory materials. This ternary system has not been explored so far. In the current work, experimental techniques such as differential thermal analysis (DTA), scanning electron microscopy (SEM) with energy dispersive spectrometry (EDS), X-ray powder diffraction (XRD) and electrical conductivity tests were used for characterization of the prepared ternary Ge-In-Zn alloys. Investigated alloys were from four isothermal sections at 25, 100, 200 and 300 degrees C and three vertical sections Ge-InZn, In-GeZn, Zn-GeIn. The obtained results were compared with the results of thermodynamic calculation of phase equilibria based on the Calphad method. The calculation was performed by using thermodynamic parameters for constitutive binary systems. Good agreements between calculated phase diagrams and experimental data have been obtained without introducing ternary thermodynamic parameters. Based on that, calculations of liquidus projection and invariant reactions were performed.

AB  - Mechanical   and   electrical properties   of   the   ternary   Bi-Ge-Sn   alloys   were investigated in this study. Calculation of isothermal section at 200, 300, and 25 ºC was carried  out  by  using  optimized  thermodynamic  parameters  for  the  constitutive  binary systems.  Microstructures  of  alloys  were  observed  by  using  optical  microscopy  and scanning electron  microscopy (SEM). Phases in  microstructures have  been detected by X-ray  diffraction  (XRD)  analysis  and  compositions  of  the  phase  by  energy  dispersive spectrometry (EDS). EDS results were compared with the predicted isothermal section at 200  and  300  ºC,  and  good  agreement  has  been  reached  between  them.  The  Brinell hardness and electrical conductivity of selected alloys were measured.  Through ANOVA analysis  and  application  of  the  obtained  results,  an  appropriate  mathematical  model  is proposed for every composition of alloys. By using the appropriated mathematical model for  Brinell  hardness  and  electrical  conductivity,  isolines  for  those  properties  were presented.

AB  - Numerous mechanical structures and assemblies have frequent outages
because of wear of machine parts due to the effects of abrasion and erosion.
There are several methods to protect parts from wear and one of them is by
applying a protective coating on the endangered area. It is well known that the
coatings with carbide distributed in a metallic matrix have an excellent wear
resistance. In this paper characterization of three coatings were carried out:
coating with tungsten carbide (WC) in NiBSiFe matrix, coating with chromium
carbides (CrC) in FeNiSi matrix deposited by plasma transferred arc method (PTA), as well as, coating with WC carbide in CrNiBSi matrix deposited by oxy-acetylene thermal spray process. The above mentioned alloys, before application to the base material, were in a powder state. This paper describes applied coating technologies on a substrate - S235JR steel, powders characteristics,
microstructure and properties of coatings, phase composition, and micro hardness of different microconstituents.

AB  - Service life extension of machine parts and equipment are increasingly being based on protection of certain, particularly endangered areas, by applying the coating. In order to increase the resistance of mechanical parts, exposed to severe service conditions, such as corrosion or wear, different type of coatings are applied. The applied coating typically have different chemical composition and characteristics compared to the base material (substrate). There are a various coating processes, which include the large group of processes, called thermal spraying. High velocity oxygen fuel spraying - HVOF, can be singled out as one of the thermal spray coating process of the new generation. HVOF process provides coatings of high quality with low oxide content, low porosity and excellent bonding strength. This paper presents an overview of the development history of HVOF process with some examples of its industrial applications, using different types of coating materials.
