“…The recorded curves look typically for the lead electrode and are characterized by the same proc-esses [6]. Figure 1 indicates that barium introduction into the Pb-Sn-Ca alloy leads to a shift of the peaks corresponding to the processes of lead oxidation to lead sulfate (Figure 1(a)) and that of lead sulfate to lead dioxide (Figure 1(b)), towards the positive side.…”

“…In these conditions, PbO 2 is formed. Figure 3 shows Nyquist plots for the electrodes made of the examined alloys with a corrosion ayer formed under potentials of 1.3 V and 1.7 V. For l data processing, the equivalent circuit (Figure 4) was used, earlier proposed for interpretation of frequency spectra with an oxide film appeared on the lead electrode at E = 1.3 V and 1.7 V [6]. Rs corresponds to the ohmic resistance of the electrolyte.…”

“…The resistance of the anode films formed under these conditions has the lowest value among all studied films at other potentials ( Table 3). In this case, the equivalent circuit, well approximating the electrode impedance, consists of a block of the capacity C of the double layer and the resistance R connected in parallel, which, in turn, is connected in series to Rs (the ohmic resistance of the electrolyte) (Figure 7) [6]. an oxide film on their surface formed at a potential 2.05 V are given in Table 3.…”

The effect of barium additives on the process of anodic corrosion of lead-tin-calcium alloys in a 4.8 М sulfuric acid solution was studied. Cyclic voltammetry, impedance spectroscopy, weight loss measurements and scanning electronic microscope analysis have allowed exploring the oxidation process and characterizing the formed corrosion layer. According to our results, barium introduction into lead-tin-calcium alloys increases their hardness, reduces their electrochemical activity, and improves their corrosion stability. Reduction of the calcium content in the alloy can be compensated by adding barium. Barium dopation at lead-tin-calcium alloys decreases the resistance of the oxide layer formed on the grid surface, in a deeply discharged state, and raises its resistance during floating conditions and at a charged state of the positive electrode.

“…The battery grids will become having higher utilization of active material and producing more uniform discharges. [1][2][3][4] It is well known that the alloying content plays an important role in the improvement of the battery grids properties. In this study, addition of alloying elements to Pb has been studied for a wide range of alloy compositions.…”

Effect of indium alloying in various concentrations with lead on both microhardness and crystallite structure of lead-indium alloy was investigated. The corrosion behavior of leadindium alloys in 4 M H 2 SO 4 acid solution was investigated by Tafel plot and electrochemical impedance spectroscopy (EIS) methods. The results of both Tafel plot extrapolation and EIS measurements exhibited the same trend. Generally, the corrosion resistance of the alloy is more significant compared with that observed for pure lead. This study shows that the addition of 0.5 pct In to Pb decreases the corrosion. However, with a further increase of alloying In, the corrosion rate of alloy starts to increase up to 5 pct In compared with that of Pb-0.5 pct In alloy. Then the corrosion rate decreases gradually with the increase in the percentage of In up to 15 pct. The values of activation energy (E a ) supported this trend of the corrosion rate which is obtained for Pb and Pb-In alloys. X-ray diffraction data exhibited broadness of peaks, which is due to lattice distortion or grain refinement. Clearly the peaks shift to higher angles for Pb-15 pct In alloy which can be attributed to changes in lattice structure of Pb. Scanning electron microscope images confirmed that the microstructure is changed with indium alloying content. The solute content tends to refine the microstructure array.

“…These researches have indicated that the performance of PbO 2 electrode is influenced significantly by metal oxide particles. Nevertheless, some restrictions are imposed on the use of pure lead as a substrate according to the possibility of Pb release during the decontamination process [32]. The substitution of Pb by other environment friendly substrates is very interesting for potential application.…”

A B S T R A C TPbO 2 films are electrodeposited by the galvanostatic (G) and pulsed current (P) methods on lead and stainless steel (AS30), respectively. They are used as electrodes for electrochemical degradation of Amaranth dye. The scanning electron microscope, atomic force microscope, and X-ray diffraction analyses revealed the dominance of β-PbO 2 form in two anodes and the absence of the form tet-PbO and PbSO 4 in AS30 substrate that have more amorphous shape and less roughness (200 nm). A poor lead oxide adhesion on AS30 substrate is detected. Cyclic voltammetry results showed that the absence of oxidation peak in the case of AS30/PbO 2 anode is related to the oxidation of PbSO 4 to β-PbO 2 . EIS results demonstrated that the pH influences largely PbO 2 layer. Concerning E123 degradation, 95 and 91% of color removal (82 and 76% of Chemical oxygen demand removals) were achieved using Pb/PbO 2 and AS30/PbO 2 anodes, respectively. In this case, current efficiency has kept relatively a high value assuming less energy consumption.
