2020年4月24日 · We compare potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), and linear polarization resistance (LPR) techniques for screening of the inhibitors over time.

2022年3月17日 · Corrosion is often investigated electrochemically by potentiodynamic polarization (PDP) experiments, both at the macro 7, 8, 9, 10 and micro 11, 12, 13, 14, 15 scales. However, the corrosion...

2020年8月30日 · The electrochemical (EIS) analysis was carried out in the same glass three-cell assembly connected with the electrochemical workstation which was used for PDP analysis using an amplitude of 5 mV, over a frequency interval from 100 kHz to 0.010 Hz. In order to ensure reproducibility, all EIS tests were rehashed multiple times.

2024年9月1日 · A study employed EIS, PDP and theoretical calculation techniques to reveal chalcone's inhibitive and adsorptive behaviour as a sustainable and effective copper’s corrosion barrier in an HNO 3 environment.

2022年5月5日 · Traditional electrochemical techniques such as EIS, linear polarization (LP), and potentiodynamic polarization (PDP) can be used to understand the corrosion behavior of metals, alloys, and coatings. Among these traditional techniques, EIS and LP have the advantage of being nondestructive in nature but have the limitation that the corrosion ...

Results from potentiodynamic polarization measurements show that inhibition efficiency increased with inhibitor concentration at 28 °C of 91.9 % and 87.0 % values respectively for D1 and D2 at 10...

the EIS can provide information on the mechanism of corrosion inhibition, while gravimetry offers a direct measurement of the rate of corrosion. And by combining SEM imaging with EDS analysis, we can provide valuable information about the microstructure, elemental composition, and surface topography of various mild steel surfaces.
