| Abstract: |
| Magnesium and its alloys, due to their remarkable biodegradability and mechanical properties, particularly their specific strength, have gained widespread attention and are being increasingly utilized as a green engineering material. However, their reactive chemical nature makes them susceptible to corrosion, limiting their widespread application. Surface modification techniques now serve as an effective means of enhancing the corrosion resistance of magnesium alloys. Layered double hydroxide (LDH), a layered structural material, has the ability to adsorb corrosive ions, thus protecting the magnesium alloy substrate. Reports indicate that the Al content in magnesium alloys can affect the LDH content in steam coatings, which in turn affects the corrosion resistance of these coatings. However, the impact of introducing Al outside the magnesium alloy substrate on corrosion resistance remains unclear. |
