a V(t) characteristic curves obtained for galvanostatic anodization (J = 100 mA/cm2) in 0.03 M oxalic acid fortend = 30 min under different conditions. From top to bottom:dotted line: same conditions as in Fig. 1a (i.e., with cooling and without stirring) but the 10-fold diluted EL.Dashed line: RT, no stirring.Continuous line: RT, stirring.Thick line: cooling, no stirring, IL2 additive withc = 0.5% v/v.Thick gray line: cooling, no stirring, IL1 additive with c = 0.5% v/v.b Values ofvgmeasured fortend = 30 min, for different combinations of IL2 relative concentrationc and current densityJ.
