The oxidation period was varied from 100 s to 300 s to understand the correlation between energy consumption and cerium incorporation, as well as its impact on the structural and corrosion resistance of the PEO film. To obtain a mechanistic understanding of the role of cerium, the structural properties before and after immersion in 3.5 wt% NaCl solution were analyzed to determine how cerium functions as an active corrosion inhibitor when incorporated into the PEO layer. The findings revealed successful and uniform cerium incorporation throughout the PEO coating (up to a 200 s oxidation time). The inhibitory effect of Ce was evidenced by the increase in the impedance modulus (Z0.01 Hz), which was up to twice as effective as that of PEO without cerium.

However, fabricating such structures on metal surfaces remains a challenge with conventional techniques. To address this, laser powder bed fusion (LPBF) was employed to fabricate a mushroom-like macrostructure array on Ti-6Al-4V, enabling the simultaneous fabrication of both the substrate and the array. Following electrochemical polishing, hydrothermal synthesis, and chemical modification, a dual-scale bionic superhydrophobic surface was developed. The combination of the mushroom-like macrostructure array, flower-like TiO2 particles, and fluorine-containing functional groups plays a crucial role in enhancing wettability control. Consequently, the surface achieves a water contact angle (WCA) exceeding 155° and exhibits aerophilicity underwater, allowing it to remain dry even when fully immersed. A systematic performance analysis demonstrated notable improvements in corrosion resistance, anti-icing performance, and durability. The corrosion current density decreased from 6.53 μA/cm2 to 0.67 μA/cm2, an order of magnitude decrease compared to the Ti-6Al-4V plate. At −15 °C, the surface significantly extended droplet freezing time and suppressed frost formation. Moreover, the surface maintained a WCA above 155° after 72 h of immersion in a 3.5 wt% NaCl solution and retained hydrophobicity even after 2000 mm of wear on 800# SiC sandpaper. This LPBF-based approach offers a scalable and durable strategy for fabricating metallic superhydrophobic surfaces.</div></div>","PeriodicalId":22009,"journal":{"name":"Surface & Coatings Technology","volume":"504 ","pages":"Article 132044"},"PeriodicalIF":5.3,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MoS2 structures exhibit distinct triangular shapes with spiral growth patterns, indicative of strong substrate-layer interactions facilitated by screw dislocations. The initiation of spiral growth is influenced by substrate characteristics, which serve as active sites for layer-by-layer deposition. Raman spectroscopy revealed peaks at 176 cm−1 (A1g(M) + LA(M)) and 228 cm−1 (LA(M)), signifying structural integrity of the MoS2 layers. Key vibrational modes such as E12g at 383 cm−1 and A1g at 408 cm−1 were associated with in-plane and out-plane dynamics, respectively. Variations in peak positions and their relative intensities can provide information about the presence of a few or multi-layer MoS2. Additional peaks at 418 cm−1, 454 cm−1 (2LA), and 465 cm−1 (A2u) suggested complex vibrational interactions in multilayer configurations. Atomic Force Microscopy (AFM) confirmed the spiral growth morphology of MoS2 structures.
