Abstract

Highly oriented Mg-Al layered double hydroxide (LDHs) films were deposited on magnesium alloy AZ31 with different deformation processes by an easy in-situ growth method.The characteristics of the films were investigated by optical microscopy (OM),X-ray diffraction (XRD),scanning electron microscopy (SEM),and electrochemical,immersion and hydrogen evolution tests.The corrosion protection performance ranked the LDHs films as the increasing series: CS-LDHs (as-cast sample with LDHs) ＜ AE-LDHs (asymmetric extrusion sample with LDHs) ＜ SE-LDHs (symmetric extrusion sample with LDHs) ＜ RS-LDHs (rolled sample with LDHs).A thicker and more compact LDH conversion coating was formed on the RS sample,and had the best corrosion protection performance.
