The presence of the different anions was confirmed by XPS measurements. Electrochemical Impedance Spectroscopy measurements were performed in order to study the electrical behavior of the films, with different inorganic anions intercalated in the LDH interlamellar space. The values of ionic conductivity ...

X-ray photoelectron spectroscopy (XPS), time-of-flight secondary ion mass spectrometry (TOF–SIMS), Fourier-transform infrared spectroscopy (FT-IR), Raman spectra and other spectral analysis techniques can be used to analyze the composition of SEI films. The SEI composition on Zn anode is analyze...
Numerous studies on Zn-Al-Mg coated steel have reported that the protective corrosion products, such as simonkolleite (Zn5Cl2(OH)8·H2O) and layered double hydroxides (LDH), contribute to corrosion reduction through their compact morphology, low electron density, and hindered ion transport across ...
