“…However, the poor corrosion resistance makes it prone to corrosion, which hinders its practical application. To improve its corrosion resistance, various treatment methods have been proposed, including conversion coating method [2,3], surface modification [4,5] and chemical inhibition [6,7]. As a highly economical, effective and practical method, conversion coating method has attracted extensive attention [8][9][10].…”

Magnesium alloy has attracted wide attention for excellent properties but poor corrosion resistance hinders its application. The method of preparing high-performance corrosionresistant films with low cost and easy operation is significantly crucial to the corrosion protection of magnesium alloy. By synthesizing zeolite film directly on AZ91D magnesium alloy, the work presented a simple, efficient and environmentally-friendly preparation method. In this study, a one-step synthesis method of multi-structure composite film on AZ91D magnesium alloy was explored. The prepared film surface had dense Mg(OH) 2 bottom layer and K 2 Al 2 Si 4 O 12 •xH 2 O upper layer with porous support microstructure. Compared with the substrate, the corrosion current on the sample surface modified by stearic acid was reduced by about three orders of magnitude, and the corrosion inhibition rate reached 99.96% with a stable contact angle of about 125°. The results showed the excellent corrosion resistance and stable hydrophobicity of the prepared sample.
