AB  - Stability of the gold complex based on mercaptotriazole in two acid electrolytes with different pH values and in a neutral medium was investigated in this work. Investigation was performed by visual monitoring and electrochemical characterization of the electrolytes in a period of one year or until first visible signs of complex decomposition. Electrochemical characterization of the gold complex based on mercaptotriazole was performed by open circuit potential measurement, cycling voltammetry method and by recording the polarization curves. The pH values of the electrolytes were measured before and after each electrochemical experiment. These tests were performed at different starting pH values: 2, 4 and 7 at optimal concentration of gold in the electrolyte of 2.5 g/dm(3). For electrolytes with pH values of four and seven, the first visible signs of the complex decomposition appeared tree months after synthesis. Electrolyte with pH value of two was visually stable for a period of one year.

AB  - The aim of this work was to investigate the stability of the gold complex based on mercaptotriazole at optimum pH value of nine in the electrolyte with gold concentration of 1.5 g/dm3. Investigations were performed by visual monitoring and electrochemical characterization of electrolytes over the period of four months. The first visible signs of the decomposition of the complex were appeared one month after synthesis. Electrochemical characterization of gold complex base on mercaptotriazole performed by the open circuit potential measurement, cycling voltammetry method, and recording the polarization curves, with pH of the electrolyte measurement before and after each electrochemical experiment, showed that all the recorded characteristics remained almost unchanged for a period of four months.

AB  - The aim of this work was to investigate the effects of current density, temperature, pH and concentration of ethyl-hexilsulfonate additive on the microhardness of electrochemically deposited gold decorative coatings obtained from a conventional cyanide electrolyte and gold complex based on mercaptotriazole. Mechanically and chemically prepared brass samples were first nickeled from acidic electrolyte. Nickel was a substrate deposit, and then decorative gold coatings were deposited from two types of electrolytes at different current densities and temperatures. Decorative gold coatings were deposited from auri-mercaptotrizole at different pH values and from electrolyte with and without the ethylhexilsulfonate additive. The microhardness of the gold coating was measured using the Knoop method. The highest values of microhardness were obtained at a current density of 1 A dm(-2) at room temperature for both electrolytes. The microhardness of the gold coatings from cyanide electrolytes was HK = 740 MPa, and the coatings obtained from auri-mercaptotriazole HK = 660 MPa. This difference is not relevant for decorative purposes. The highest values of microhardness, HK = 660 MPa, were obtained at pH = 9 from the gold complex based on mercaptotriazole without the additive.

AB  - In this paper, changes in the mechanical properties of Pd-5Ni alloy are analysed after recrystallisation annealing in order to determine the optimal conditions for a thermomechanical processing regime for this alloy. The temperature and annealing time were varied and the resulting changes in hardness, tensile strength, relative elongation and proof strength were monitored. By using the simplex-lattice method and analysing experimental data, a fourth degree mathematical model-regression polynomial was defined and isolines of changes in the mechanical properties of the investigated alloys were designed depending on the conditions of heat treatment after rolling.

AB  - The paper presents the results of investigation the influence of rhodium as an alloying element on the mechanical properties of platinum. A short-term and tensile strength were tested, at room and high temperatures, and also sliding rate and time to the destruction of the Pt-Rh system alloys at high temperatures. The results showed that alloying with rhodium strengthens the platinum while reducing its plasticity. Time to destruction is much longer in Pt-Rh alloys compared to pure platinum.

All mass spectra were obtained using laser desorption ionization (LDI) method on a commercial matrix assisted laser desorption ionization – time of flight (MALDI-TOF) mass spectrometer. The LDI MS spectra of chloroauric acid gave evidence of the presence of a variety of monomeric and polymeric complexes. LDI MS spectra of the electrolyte obtained from chloroauric acid, glycine and mercaptotriazole revealed existence of the ion at m/z 472 which indicated that the complex [Au(NH2CH2COOH)(C2H2N3S)2]- has been formed.

AB  - We investigated the effects of natural seawater on the corrosion of an Ag43Cu37Zn20 alloy. The alloy was a commercial brazing filler alloy of composition (BS1845:1984 Ag5) and belongs to the class of Cd-free silver brazing alloys. The Ag-Cu-Zn system is corrosion resistant in chloride solutions has not been widely examined. In this study, the corrosion behavior of the alloy has been investigated using the open circuit potential measurements, Tafel plots and anodic potentiodynamic curves. By comparing different samples of marine water indicates that salinity is the primary influence on corrosion behavior near the open circuit potential. At higher anodic potentials, the impact of mineral composition becomes significant.

AB  - Cilj rada bio je komparativna karakterizacija elektrohemijskih prevlaka zlata dobijenih iz sveže sintetisovanog elektrolita, elektrolita nakon godinu dana od sinteze i elektrolita dobijenog rastvaranjem kristala komleksa zlata na bazi merkaptotriazola. Spoljni izgled, debljina, hrapavost, mikrotvrdoća po Knoopu i elektronska mikroskopija (SEM sa EDS-om) prevlaka pokazali su da su prevlake dobijene iz sva tri elektrolita svetle sa dobrim prianjanjem. Najmanja hrapavost je izmerena za prevlake dobijene iz svežeg elektrolita, a najveća za prevlake dobijene iz elektrolita dobijenog rastvaranjem kristala. U pogledu tvrdoće ne postoje značajne razlike.
AB  - The aim of this work was A comparative characterization of electrochemically deposited gold decorative coatings obtained from the fresh synthesized electrolyte, then the electrolyte aged for a year and coatings obtained from the electrolyte by dissolving crystals of gold-mercaptotriazole. The external appearance of coatings, thickness, surface roughness, the Knoop microhardness and electron micros- copy (SEM with EDS) have showed that the coatings obtained from all three electrolytes are bright and with a good adhesion. The smallest roughness was measured for the coating obtained from fresh electrolyte and the greatest for the coating obtained from electrolyte obtained by dissolving crystals. In terms of hardness, there are no significant differences.

AB  - The goal of this paper was to study the influence of organic gold complex based on mercaptotriazole on photoresist layers used in manufacturing of printed circuit boards (PCBs). Investigations were performed by immersion the previously prepared boards in electrolytes with different pH values (pH=2, 4, 7, 9 and 12) at gold concentration of 2.5 g/dm3 and in gold complexes with different gold concentrations (1.5; 2.0; 2.5; 3.0 and 3.5 g/dm(3)) at pH value of pH=9. Investigations showed that photoresist layers on boards are the most resistant at optimal operating conditions, pH=9 and concentration of gold of 2.5 g/dm(3).

AB  - The surface reconstruction on rhodium-platinum catalyst gauzes has been examined using the scanning electron microscope techniques. The nucleation and growth of large cage-like features, developed on the gauze surfaces during operation in the ammonia oxidation process, were studied in detail. It is concluded that a vapor phase mechanism involving transport of platinum oxide is responsible for the observed reaction, and the reason why this process operates only over a limited range of temperature and pressure is explained. Some comments are also made on the related reconstruction observed on gauzes, used during the production of hydrogen cyanide by the Andrussow process.
