Chlorides Entrapment Capability of Various In-Situ Grown NiAl-LDHs: Structural and Corrosion Resistance Properties
Source abstract
Abstract
In this work, various NiAl-LDH thin films, exhibiting specific surface morphologies, were developed directly on aluminum AA 6082 substrate to understand the two main characteristics of layered double hydroxide (LDH), i.e., ion-exchange behavior and barrier properties, which are found to have a significant influence on the LDH corrosion resistance properties. The as-prepared NiAl-LDH films were analyzed through the scanning electronic microscope (SEM), X-ray diffraction (XRD), while the corrosion behavior of the synthesized films was investigated by the electrochemical impedance spectroscopy (EIS) and potentiodynamic curves. The results indicated that NiAl-LDH microcrystals grow in various fashions, from porous relatively flat domains to well-developed platelet structure, with the variation of nickel nitrate to ammonium nitrate salts molar ratios. The LDH structure is observed in all cases and is found to cover the aluminum surface uniformly in the lamellar order. All the developed NiAl-LDHs are found to enhance the corrosion resistance of the aluminum substrate, specifically, a well-developed platelet structure is found to be more effective in chloride adsorptive and entrapment capabilities, which caused higher corrosion resistance compared to other developed NiAl-LDHs. The comparison of the synthesized NiAl-LDH morphologies on their ion-exchange capabilities, barrier effect and their combined effect on corrosion resistance properties is reported.
