Layered double hydroxides (LDHs) were grown directly on γ, α, and amorphous Al2O3 powders, respectively, in order to investigate the phase responsible for in-situ LDH growth on PEO coating. Furthermore, it is shown that LDH growth is limited by the high tortuosity of the PEO layer and the accessibility of Al(OH)−4 anions from the substrate covered with thin amorphous aluminum oxide, through the pores.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttps://doi.org/10.3390/coatings7110190https://www.mdpi.com/2079-6412/7/11/190open accesslayered double hydroxidesplasma electrolytic oxidationaluminum alloyIngeniería químicaMateriales3303 Ingeniería y Tecnología Químicas3312 Tecnología de Materiales
