چکیده انگلیسی
This study aims at synthesis and characterization of Zn-Al-PO43â and Zn-Al-NO3â layered double hydroxides (LDHs) through employing FE-SEM, EDS and X-ray photoelectron spectroscopy (XPS) analyses. The smart release ability of the inhibitive spices from LDHs were checked by EIS, polarization and surface analysis tests in 3.5Â wt.% NaCl solution. A two-layer coating system consisting of silane primer filled with LDHs and epoxy-polyamide top coat were applied on steel and then the active inhibition capability of the coatings was investigated. The addition of Zn-Al-PO43â LDH to the silane coating provides efficient inhibition behavior by releasing PO43â anions through ion exchange process.
