“…The results obtained are shown in Figure 7 and Table 5. As seen in Figure 7, an increase in the concentration of chloride ions leads to a shift in the potential of Cu24Zn5Al in the negative direction [32,60] after 60 min of immersion in a 0.017 mol/dm 3 PMT solution. The current density is higher in all solutions containing chloride ions in comparison to the current density in the sodium sulfate solution measured under the same conditions, but significantly lower than the current densities obtained by polarization in solutions with chloride ions of the same concentration, without 60 min of immersion in a 0.017 mol/dm 3 PMT solution.…”

The results of this research on the electrochemical behavior of Cu24Zn5Al alloy in a 0.1 mol/dm3 sodium sulfate (Na2SO4) solution containing 1-phenyl-5-mercaptotetrazole (PMT) are presented in this paper. The influence of PMT concentration, chloride ion concentration, and pre-treatment were examined. The influence of pre-treatment was studied in terms of the effect of the immersion time of the electrode in the appropriate inhibitor solution. After selecting the optimal immersion time, its effect on the behavior of the Cu24Zn5Al alloy was tested in a 0.1 mol/dm3 solution of sodium sulfate in the presence of different concentrations of chloride ions. Research shown that with the increase of PMT concentration, the anodic current density around the corrosion potential decreases, indicating that PMT behaves as a corrosion inhibitor for Cu24Zn5Al alloy.
