This study explores the use of concentrated sulfuric acid (70 % H₂SO₄) for titanium surface preparation under various temperatures (20 °C and 50 °C) and immersion times (15 and 30 min). Surface modifications in morphology and composition are analyzed using SEM, GDOES, XRD, and XPS techniques. Mild etching conditions (low temperatures and short durations) have been proven to be insufficient for removing surface contaminants, such as titanium carbide. On the contrary, harsher conditions (extended immersion times or/and higher temperatures) effectively eliminate impurities but result in hydrogenation of the titanium surface. In this case, a titanium hydride layer (TiH₂) appears on the surface, modifying its morphology and roughness. On this occasion, the combination of XRD and GDOES techniques proves to be effective in revealing the presence of hydrides. Moreover, hydrogenation significantly increases with immersion time and temperature. Eventually, the impact of etching conditions on anodic film corrosion properties is also evaluated by EIS measurements. The study highlights that performances of anodic films are strongly influenced by the etching parameters. Indeed, titanium hydride layers can adversely affect corrosion resistance of anodic films. Therefore, to ensure optimal results, etching conditions must strike a balance between thorough cleaning and minimizing hydrogenation, thereby preserving the corrosion resistance of anodic films.</div></div>","PeriodicalId":34303,"journal":{"name":"Applied Surface Science Advances","volume":"27 ","pages":"Article 100767"},"PeriodicalIF":7.5,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143937735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By utilising the compositional gradient of the as-deposited coatings, ten candidates with varying Zr contents were evaluated. Among them, the coating with 0.15 wt.% Zr exhibited the best oxidation and corrosion resistance. Results show that moderate Zr doping promotes the θ-Al₂O₃ to α-Al₂O₃ transformation and delays the β to γ/γ′ phase transition, leading to the formation of a dense and smooth oxide scale. However, EBSD analysis reveals that increasing Zr content coarsens the grain size, and excessive Zr accelerates Al depletion and promotes spinel formation. During oxidation, a semicoherent γ/γ′ to α-Al₂O₃ interface is formed, whereas in corrosion-tested samples, the β-NiAl to α-Al₂O₃ interface becomes incoherent, weakening interfacial bonding. Nevertheless, Zr diffusion from the coating into the thermally grown oxide (TGO) forms Zr-rich bands, which significantly inhibit Al outward diffusion. Thermo-Calc simulations indicate that the volume fraction of β-NiAl at 1100 °C (low Al content β-NiAl) is much higher than at 900 °C (high Al content β-NiAl), and that Zr has little effect on the overall phase distribution.

However, hydrogen production via ammonia decomposition faces various challenges. Although ruthenium (Ru) catalysts exhibit the highest activity for ammonia decomposition, their scarcity and high cost hinder commercial application. Consequently, nickel (Ni) catalysts have emerged as a potential alternative, owing to their cost-effectiveness and high activity. To further optimize Ni catalysts, developing Ni-based alloy catalysts with other metals is a promising solution. Herein, density functional theory (DFT) calculations are performed to elucidate the catalytic activity of 3d transition metals (Ni, Co, Cu, and Fe) and their promising alloys. The key reaction steps of overall ammonia decomposition are NH_x‒H bond scission (NH_x*→NH_x-1*+H*) and N + N recombination (N*+N*→N₂*). In particular, nitrogen adsorption energy (E_ad(N)) serves as a descriptor for predicting the activation energies of key elementary steps, revealing a volcano-like relationship between experimental catalytic activity and DFT-calculated E_ad(N). Additionally, we discover a strong correlation between d-band filling (f_d) and E_ad(N), establishing f_d as an effective descriptor that not only predicts E_ad(N) but also the catalytic activity of NH₃ decomposition. Our descriptor-based design principle identifies Ni_0.64Fe_0.36 as a potentially effective and cost-efficient candidate for hydrogen production from ammonia, with experimental data demonstrating its superior performance compared to pure Ni.
