Due to the presence of Si and Cu elements in the Al\u2013Si\u2013Cu alloy, the corrosion resistance of the Al\u2013Si\u2013Cu alloy is lowered. Thus, developing a corrosion-resistant film on the Al\u2013Si\u2013Cu alloy is necessary. A layered double hydroxide (LDH) film is recognized as a promising corrosion-resistant coating. LDHs exhibit a distinct structure where positively charged basic layers (metal hydroxides) are interleaved with intermediate layers that accommodate charge-compensating anions and hydration water. The positively charged layers allow for the exchange of anions as interlayers, enabling the incorporation of various anions into the interlayer. The difference in the anion species in the interlayer of the LDH films can affect corrosion-resistant performance. In this study, we aimed to prepare Mg\u2013Al LDH films intercalated with different anions (NO3\u2212, MoO42\u2212, VO43\u2212, and PO43\u2212) and investigate the corrosion resistance of the LDH films. The films were prepared on die-cast Al\u2013Si\u2013Cu alloys using steam coating and immersion processes. The prepared LDH films were characterized by XRD, SEM, FT-IR, and electrochemical measurements. The electrochemical measurements revealed that Mg\u2013Al LDH films intercalated with MoO42\u2212 showed the most superior corrosion resistance among all films prepared in this study.<\/jats:p>","DOI":"10.3390\/ma18235405","type":"journal-article","created":{"date-parts":[[2025,12,4]],"date-time":"2025-12-04T16:07:38Z","timestamp":1764864458000},"page":"5405","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Steam Coating-Based Synthesis and Corrosion Inhibition Performance of Mg\u2013Al-Layered Double Hydroxide Films with Different Interlayer Anions on Al-Si-Cu Alloys"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-4343-5868","authenticated-orcid":false,"given":"Io","family":"Matsui","sequence":"first","affiliation":[{"name":"Materials Science and Engineering, Graduate School of Engineering and Science, Shibaura Institute of Technology, Tokyo 135-8548, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hikari","family":"Ouchi","sequence":"additional","affiliation":[{"name":"Materials Science and Engineering, Graduate School of Engineering and Science, Shibaura Institute of Technology, Tokyo 135-8548, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuki","family":"Atsuumi","sequence":"additional","affiliation":[{"name":"Materials Science and Engineering, Graduate School of Engineering and Science, Shibaura Institute of Technology, Tokyo 135-8548, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kota","family":"Fukuhara","sequence":"additional","affiliation":[{"name":"Materials Science and Engineering, Graduate School of Engineering and Science, Shibaura Institute of Technology, Tokyo 135-8548, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6177-7890","authenticated-orcid":false,"given":"Takahiro","family":"Ishizaki","sequence":"additional","affiliation":[{"name":"College of Engineering, Shibaura Institute of Technology, Tokyo 135-8548, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"276","DOI":"10.1002\/maco.201206691","article-title":"Corrosion protection of pure aluminium and aluminium alloy (AA7075) in salt solution with silane-based sol-gel coatings","volume":"64","author":"Younis","year":"2013","journal-title":"Mater.
