After electrically insulating the tube, a lithographic masking strategy adapted to the cylindrical surface was employed. The surface was functionalized with silanes to deposit a catalytic surface composed of palladium and tin. Non-critical materials such as copper and nickel were selected as sensor materials, depositing them over the catalytic surface by electroless plating.

The electrical results for the copper sensing layer evidenced the need for a protective layer. Silicon oxide was chosen as a protective material. However, it was observed that the sensing and protective layers interact due to their chemical affinity. In contrast, the electrical response of the nickel circuit was stable and repeatable after thermal cycling (heating and cooling), indicating that protection was not necessary for the working temperature range.

Film chemistry was characterised by X-ray photoelectron spectroscopy while film thicknesses on non-porous substrates deposited at the same time as the pSi substrates were measured using spectroscopic ellipsometry.

For the three pSi substrates, with pores diameters <180 nm, negligible film penetration into the pores was observed in the HIM images. Continuous films were observed, completely occluding the pores when the ppAAc films were thicker than the diameter of the largest pores. For pSi with pore diameters of 0.9–1.2 μm, ppAAc film was observed up to 2 μm inside the pore.

Currently, the most effective method is to incorporate a hydrogen permeation barrier layer on the inner surface of the pipelines. Therefore, this paper employs plasma spraying technology to prepare Cr<sub>2</sub>O<sub>3</sub> and Cr<sub>2</sub>O<sub>3</sub>–10%TiO<sub>2</sub> hydrogen permeation barrier coatings and combines first-principles calculations based on density functional theory to explore in depth the synergistic effects of Cr<sub>2</sub>O<sub>3</sub> and TiO<sub>2</sub> on hydrogen permeation resistance. Experimental results indicate that the doping of TiO<sub>2</sub> not only significantly enhances the surface smoothness of the coating but also effectively reduces pore defects. This improvement directly prolongs the time required for hydrogen atoms to penetrate the coating and decreases the hydrogen permeation current density, thereby greatly enhancing the hydrogen barrier performance of the coating. Furthermore, first-principles calculations reveal that the hydrogen permeation resistance mechanism of the composite coating primarily relies on two core aspects: on the one hand, its dense crystalline structure and stable chemical bond structure effectively hinder the adsorption process of hydrogen atoms on the coating surface, slowing down the permeation rate of hydrogen atoms. On the other hand, once hydrogen atoms successfully penetrate the interior of the hydrogen permeation barrier layer, they are trapped by interstitial sites and vacancies within the coating, effectively preventing further diffusion of the hydrogen atoms.</div></div>","PeriodicalId":22009,"journal":{"name":"Surface & Coatings Technology","volume":"507 ","pages":"Article 132156"},"PeriodicalIF":5.3,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143835265","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}

Coatings combining calcium carbonate (CC) and hydroxyapatite (HA) are particularly effective in mimicking natural calcified tissues, embodying the principles of fourth-generation biomaterials. Existing techniques largely constrain the development of fully functional CC/HA coatings. Concurrently, plasma electrolytic oxidation (PEO), one of the most prospective approaches for metallic surface chemical modification, remains underexplored in the context of carbonates. This paper comprehensively reviewed the challenges and limitations associated with the parallel incorporation of CC and HA into PEO coatings, focusing on the additives' aggregate state, physicochemical properties, synthesis methods, and PEO process parameters. Additionally, an optimum strategy for creating Ti-based CC/HA coatings was identified via deductive approach and causal analysis. Standard PEO baths comprising only soluble components were recognized as inapplicable, whereas those representing biphasic particle suspensions exhibited undeniable advantages for the stated purpose. The ultimately preferred bath recipe consisted of CC particle suspension synthesized via carbonation route and further subjected to competing dissolution-precipitation and chemisorption reactions in dibasic sodium phosphate electrolyte.

This behavior hinders process stabilization and can lead to a modification of the desired film properties. This study investigates the processes behind this behavior by performing time-resolved measurements during reactive sputtering of aluminum in argon/oxygen mixtures. Two distinct groups of physical processes were identified. The first group exhibits a relatively fast time-dependent behavior, leading to process stabilization within 5 to 8 min. This group includes processes related to reactive gas introduction, its interaction with deposited material, and the feedback loop characteristics. The second group causes a continuous drift of the process for more than 45 min, primarily due to oxide deposition on the chamber walls and target erosion. These two groups have a different impact on the process curves known as hysteresis curves. For the first group, the impact is minimal while for the second group the hysteresis curve becomes distorted, potentially leading to misinterpretation or incorrect selection of deposition conditions. The utilization of the difference between the discharge voltage and floating potential as the feedback input signal eliminates the impact of oxide deposition and mitigates this problem.</div></div>","PeriodicalId":22009,"journal":{"name":"Surface & Coatings Technology","volume":"507 ","pages":"Article 132095"},"PeriodicalIF":5.3,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143823736","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}
