A bimodified MgAlCe-LDHs@GO self-healing anti-corrosion coating based on the micro arc oxidation coating of AZ31 magnesium alloy
To obtain magnesium (Mg) alloys with long-term corrosion resistance, coatings with enhanced stability and self-healing effect are necessary. This study in-situ produced a layered double hydroxides (LDHs) coating using hydrothermal method to process the cerium salt treated micro arc oxidation (MAO) coating in sodium dodecylbenzene sulfonate (SDBS)-modified graphene oxide (GO) solution (MgAlCe-LDHs@GO-SDBS), and further introduced 3,5-dinitrosalicylic (D) acid and quinolizic acid (Q) via anion-exchange method. The multiple effects of Ce, GO-SDBS, and corrosion inhibitors significantly enhanced the coatings’ anti-corrosive and self-healing performance. The MgAlCe-LDHs@GO-S&D coating possessed significantly decreased corrosion current density of 3.6 × 10−9 A·cm−2.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena.
