A novel composite system composed of zirconia and double hydroxide layers (LDHs) was successfully fabricated on the plasma electrolysis (PE) coating. For this aim, the molybdate-loaded LDHs film grown on the PE film of aluminum alloy was modified additionally by zirconia nanoparticles via a facile dip-coating method. The MoO₄^2- anions which were obtained by anion exchange process from the precursor CeMgAl-LDH film, led to decrease the distance between the flakes of LDHs film where a flower-like structure was successfully developed. Moreover, the inclusion of zirconia helped to decrease the size of pores present in the LDHs films. Accordingly, a superior smart protective film was obtained due to the possible synergetic effects between the MoO₄^2- and Ce³⁺ ions released from LDHs film as well as the high chemical stability of zirconia. The LDHs film modified by zirconia can be regarded as a stable smart coating, meaning that it has the ability to control the release of corrosion inhibitors and providing an excellent long-term electrochemical performance as well.

在等离子体电解（PE）涂层上成功制造了一种由氧化锆和双氢氧化物层（LDHs）组成的新型复合体系。为了这个目的，在氧化铝的PE膜上生长的加载钼酸盐的LDHs膜通过易浸涂法另外用氧化锆纳米粒子改性。通过阴离子交换工艺从前体CeMgAl-LDH膜中获得的MoO ₄ ^2-阴离子导致LDHs膜片之间的距离减小，而在LDHs膜中成功形成了花状结构。而且，氧化锆的加入有助于减小LDHs膜中存在的孔的尺寸。因此，由于MoO ₄ ^2-和Ce之间可能的协同作用，获得了优异的智能保护膜。从LDHs膜中释放出³⁺离子以及氧化锆的高化学稳定性。经氧化锆改性的LDHs膜可被视为稳定的智能涂料，这意味着它具有控制缓蚀剂释放的能力，并且还具有出色的长期电化学性能。
