Figure 3From: Corrosion inhibition properties of pyrazolylindolenine compounds on copper surface in acidic media Tafel polarization curves (vs. SCE) for corrosion of Cu plates in 1 M HCl in the presence of different concentration of pyrazolylindolenine compounds (left side curves: a, c and e), Tafel plots in the right side (b and d) shows corrosion behaviour in the presence of 2.5 mM inhibitors at different temperatures.
