“…Therefore, it is necessary to develop multilayer anticorrosion systems based on LDH, which, on one side, can compensate for their drawbacks and, on the other, can achieve high corrosion protection. Combination of LDH with anodic oxidation coatings, − microarc oxidation, − and other surface modifications, ,, including paints − as post-treatments have already demonstrated their effectiveness in improving the anticorrosion properties or superhydrophobicity of coatings, showing potential for further industrialization. However, while the second component increased the barrier properties of the coating, active corrosion protection was provided only by the LDH part.…”

A novel inhibitor-loaded bilayer hybrid system based on the LDH inner layer and MOF outer layer is designed on an aluminum alloy 2A12 surface to improve corrosion performance. The hybrid film system covers the inherent cavities and intercrystalline defects of the LDH film using the affinity between the LDH and the MOF compounds. The results demonstrate that the LDH-inhI precursor film is entirely covered by new Zn-based MOF microrods. The LDH-inhI precursor film is partially dissolved and recrystallized in favor of MOF crystal growth to strengthen the binding adhesion between LDH and MOF films. The LDH-inhI/MOF-inhII bilayer film shows significantly enhanced corrosion resistance through the synergistic action of LDH and MOF nanocontainers doped with different corrosion inhibitors (vanadates, 2,5-furandicarboxylic acid, and benzotriazoles). Due to the multiple loadings of the MOF film and the sustained-release of the LDH film, this method provides an effective approach to developing new anticorrosion systems and enhancing both the barrier ability and active corrosion protection performance of LDHbased conversion treatments.

“…Magnesium alloys have the advantage of light mass and high strength, but they are also more vulnerable to corrosion than other alloys [1][2][3], especially in solutions containing Cland HCO 3 ions [4,5], so anti-corrosion studies for these solutions are key to the protection of magnesium alloys [6,7]. During the preparation of anti-corrosion coatings with magnesium alloys, the composition of the coating produced on the surface will contain magnesium hydroxide if the magnesium alloys are in an alkaline environment [8][9][10].…”

Rapid corrosion rate is limiting the engineering application of magnesium alloys. In this paper, an attempt was made to produce a corrosion resistant coating on the surface of AZ91D magnesium alloy using hydrothermal method. The coating surface is covered with microspheres and has a dense structure, which effectively isolates the contact between the outside world and the substrate. The corrosion potential(E) raised from -1.57V to -0.45V compared to the bare sample. The corrosion current density and corrosion rate of the coating can be reduced by 6 orders of magnitude, and the polarization resistance raised by 6 orders of magnitude. The thickness of the coating is 45.4 μm at the moment, with a minimum of defects on the surface, resulting in excellent corrosion resistance in the immersion test. The coating also has good adhesion strength at 4B, which can expand the application range of magnesium alloy in corrosive environments.
