In this study, an environment‐friendly composite ZnAl‐LDH film modified by the rich biomass lignin was prepared on AA 7075 surface successfully. A wide range of characterizations was carried out to obtain the morphology, composition, and structure of this composite film, including scanning electron microscopy, X‐ray diffraction, Fourier transform infrared spectroscopy (FTIR), and so on. In addition,...
Zn and frozen 3.5 wt.% NaCl solution were used to simulate galvanized steel structures exposed to the seawater in the Polar Regions. The conductivity of the frozen salt solution and the corrosion of the Zn were characterized by electrochemical impedance spectroscopy, galvanic current measurement, and surface analyses. The results indicated that the completely frozen 3.5 wt.% NaCl solution was still...
