AB  - The paper analyses the corrosion behaviour of both naturally and artificially aged AA2024 aluminium alloy in NaCl solution in the presence of the corrosion inhibitor benzotriazole (BTA). The differences between these two aging tempers in terms of resistance to general corrosion are explained as well as the differences in terms of pit formation and pit growth. Based on the values of the polarisation resistance and the corrosion current density, the general corrosion resistance of the alloy is determined in the absence and in the presence of BTA. The resistance to pit formation and pit growth is determined on the basis of the polarisation measurements results. Scanning electron microscopy confirmed the expected differences in the appearance and size of the pits formed in naturally aged and artificially aged alloy. In the presence of the corrosion inhibitor BTA, for both aging tempers of the alloy, the corrosion resistance is significantly higher compared to the resistance in the solution without the inhibitor. The value of the polarisation resistance for both aging tempers increases over time. However, at the same time, the value of the constant phase element increases as well. An explanation for this phenomenon is provided. The calculated average value of the thickness of the adsorbed inhibitor layer on the surface of the aluminium alloy is in accordance with the inhibitor protective ability for both aging tempers.

AB  - The corrosion inhibiting possibility examination of extracts obtained from fruits of rose hip and
horse chestnut was investigated. Rose hip extracted at different temperatures exhibited different
corrosion inhibiting effect. Rose hip obtained at 40oC did not show any inhibiting effect in neutral
pH medium, while in acidic media it expressed moderate protective impact (up to 55%) for steel
and mild corrosion inhibiting impact for zinc (39%), while for aluminium and copper it did not
have any inhibiting effect. Rose hip obtained at 25oC exhibited significant inhibiting effect for steel
(up to 62 %) and even better for zinc (up to 72%) in neutral media. For aluminium and copper
neither of Rose hip extracts showed any inhibiting effect. The Horse chestnut extract exhibits
moderate to significant inhibiting effect for steel (up to 55%) and zinc (up to 60%) in neutral
media. In addition to this, because of the complex chemical composition of these fruit extracts,
some further electrochemical investigation is suggested, aimed to determine a single component
inhibitive effect. Firstly, as one of prevailing components, tannins are examined. Linear
polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) were used as a
testing techniques.

AB  - Copper anodes with non-standard nickel, lead, antimony and thin content are used for refining by the standard electrochemical process. The waste solution from standard copper electrorefining process is used as working solution. Beside copper, there is а high concentration of nickel and arsine in this waste solution. The effect of nickel in maximum content of 10 mass %, the effect of lead, tin and antimony in maximum cumulative content of 3 mass %, as well as the effect of working solution temperature were investigated. Measured values for cells voltage have shown the appearance of three characteristic phases: stable phase, oscillation phase and full passivation phase, but no one full anode passivation is registered during the 72 hours of each set of experimental conditions. The results for anode mass changing have revealed that the anode dissolution is similar at two different operating temperatures. Mass balance for copper has shown that the copper cathode mass is higher than dissolved copper from the related anode. Based on data for chemical composition of working solution changing, it was pointed out that the copper concentration decreased during the process, maximum up to 1 g dm-3. Accomplished waste materials recycling have both environmental and economic effects since the cleaner environment and sustainable resources utilization mean socially responsible behavior.
