Electrochemical data obtained from the potentiodynamic polarisation curves of pure zinc and zinc alloy (Zn-5 Al-4 Mg).
| Ecorr (mVAg/AgCl) | βa (mV/decade) | βc (mV/decade) | icorr (μA/cm2) | Corrosion Rate (mm/y) | |
|---|---|---|---|---|---|
| Pure Zn | −1032 ± 5 | 318 | −417 | 9.55 ± 1.1 | 0.14 |
| Zn Alloy | −1020 ± 5 | 295 | −202 | 17.7 ± 1.2 | 0.32 |
Values represent means of triplicate samples ± absolute standard deviations.
