Electrochemical data for the coating from potentiodynamic polarization.

Diffusion Time (h) Ecorr (mV.SCE) Icorr (mA/cm2) ba (mV/dec) bc (mV/dec)
Substrate −455.42 11.17 × 10−3 132.48 −63.72
1 −354.07 6.04 × 10−3 99.19 −125.39
3 −201.14 0.514 × 10−3 96.98 −59.43
5 −231.72 0.705 × 10−3 52.90 −73.90
7 −276.62 2.68 × 10−3 101.51 −121.39

Note: Ecorr and Icorr are the corrosion potential and corrosion current density, respectively; ba and bc are the anodic and cathodic Tafel slopes, respectively.
