文摘
- •
The use of the rotating disc electrode (RDE) during polarization measurements is analyzed.
- •
The corrosion layer formed during polarization is reduced by the use of the RDE.
- •
Experimental results are in agreement with the enhanced catalytic surface theory.
- •
Polarization test reproducibility is improved when ω > 1500 rpm.
- •
The scan rate does not play an important role when RDE is applied.
