The results show that with the increase of NiSO4 addition, the oxidation voltage increases, the surface morphology is uniform and dense, and the thickness, hardness, and wear resistance of the coating are improved. The phase of the MAO coating is mainly composed of anatase, rutile, TixO, and SiO2. The self-corrosion current and corrosion rate of the MAO coating decreased significantly after the addition of NiSO4, and the corrosion resistance was improved. The results of the erosion corrosion experiment show that the 1 g/L NiSO4-modified ceramic coating can provide effective protection for the titanium alloy substrate.

This work reports the thermophysical properties of weberite-type Pr3NbO7 niobates synthesized using a solid-state reaction, and its thermal and elastic properties are the key points. It is revealed that Pr3NbO7 has characteristics of a low thermal conductivity (k = 1.05 W m−1 K−1 at 900°C) and Young's modulus (E = 106 GPa), and its thermal expansion coefficients (TECs) are 8.9 × 10−6 K−1 at 1200°C. The low thermal conductivity is related to its weberite-type structure and the differences of bonding strength between the Pr–O and Nb–O bonds, which can enhance the phonon scattering rate (E/k ratio) to reduce thermal conductivity. The modulus is mainly affected by the bonding strength, which is indicated by the Debye temperature (315 K), and modulus increases with the increasing Debye temperature for weberite-type RE3MO7 ceramics. The low thermal conductivity and modulus, as well as an excellent high-temperature stability prove that Pr3NbO7 is a promising candidate for TBC applications.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its susceptibility to catastrophic deformation limits its application. To enhance the service life of enamel, enamel composite material samples were fabricated in this study. Different proportions of zirconium diboride (ZrB2) particles were incorporated into the enamel, and the steel samples were processed through annealing, sandblasting, enamel spraying, and sintering. By comparing and studying the structure, morphology, flexural strength, fracture toughness, and alkali corrosion resistance, adding an appropriate amount of ZrB2 can significantly improve the mechanical properties and alkali corrosion resistance. The addition of ZrB2 results in a more compact microstructure within the enamel. Especially when the ZrB2 content is 4 wt.%, the bending strength of enamel reaches its highest and the fracture toughness is the best; When the ZrB2 content is 3 wt.%, the enamel exhibits the better alkali resistance, with a corrosion mass loss of 2.2 mg. In addition, adding ZrB2 in moderation can effectively reduce the porosity of enamel and improve the bonding strength between enamel and metal matrix.

Our study addresses these challenges by incorporating SPS as a post-processing step, achieving near-theoretical maximum densities and significantly reducing porosity, thereby resulting in outstanding thermal conductivity in SiC ceramics. We developed a specialized SiC ink optimized for 3D printing, ensuring structural integrity after deposition through tailored rheological properties. The application of SPS facilitates rapid, uniform sintering, essential for attaining superior density, mechanical properties, and thermal performance. Our experimental results, confirmed through scanning electron microscopy analysis, demonstrate significant microstructural properties, mechanical strength, and thermal conductivity, showcasing the effectiveness of integrating SPS in AM processes.

This review comprehensively discusses the manufacturing processes, healing mechanisms, and testing methodologies with an emphasis on enhancing self-healing capability of OISHCCs under service circumstances. Notably, we have reviewed the testing approaches of OISHCCs, which were conducted at several temperatures, that is, ≥673 K, and their respective high-temperature potential applications are listed. This review includes recent developments in rapid and repetitive fracture healing and mechanical performance recovery. However, understanding the intricate relationships between matrices, HAs, oxidative products, and oxidation kinetics which are essential for optimal composite design remains difficult, though. One important technique for examining and improving material performance is the coupling of experimental methods with finite element analysis (FEA). However, optimizing OISHCCs for realistic high-temperature applications is still difficult despite advancements. Hence, this paper outlines the present status of OISHCCs, identifies persistent issues, and makes recommendations for future research, with a focus on practical applications.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When sintering temperature (TS) is 1280–1340°C, the DGG phenomenon is observed with little change in phase structure, and grains all grow from several to tens of micrometers. Adding LiF can decrease the temperature span (Tspan) of DGG from 20°C to 10°C due to the high mobility of Li+; however, adding Li2CO3 extends Tspan from 20°C to 40°C since it decomposes and releases gas and then hinders the DGG process. Adding SiO2 and B2O3 decreases the critical TS of DGG by about 20–30°C due to their lower melting point or eutectic temperature. A higher critical TS or a narrower Tspan generally results in smaller grains and lower density before DGG, while can induce larger grains and higher dielectric/ferroelectric properties after DGG. Obvious dielectric diffuseness behavior is observed after adding Li2CO3 or B2O3 due to the smaller grains or more pores. The variation in properties is consistent with the grain size change after adding sintering aids. This work shows a fundamental understanding of sintering aids' influences on DGG and provides guidance for controlling microstructure and properties in polycrystalline ceramics.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 5","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144814738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
