Effects of Laser Scanning Speed on Microstructure, Microhardness, and Corrosion Behavior of Laser Cladding Ni45 Coatings

Figure 12

Schematic illustration of ideal polarization curves of C1 (point A, E_corr1 and i_corr1), C2 (point B, E_corr2 and i_corr2), and C3 (point C, E_corr3 and i_corr3) coatings in 0.5 M NaCl solution. The symbol c1 represents the cathodic polarization curve of all the coatings, and the symbols a₁, a₂, and a₃ represent the anodic polarization curves of C1, C2, and C3 coatings, respectively.
