Topography of sample surface after electropolishing (T = 55°C and q = 9.00 Amin·cm⁻²) in a bath without ER: (a) sample without defects (i = 0.17 A·cm⁻²); (b) sample with defects (i = 0.19 A·cm⁻²); (c) sample with defects (i = 0.20 A·cm⁻²); and (d) after electropolishing in a bath with ER with defects (i = 0.20 A·cm⁻²).
