Therefore, this study is devoted to the detection of macro-micro cracks in pipes with silicate-enamel coatings, which are commonly used to enhance corrosion resistance. While the process of detecting macro cracks on the surface of the coating is currently underway, the identification of macro-micro cracks remains a significant challenge. The article highlights the significance of their timely detection to prevent potential leakage and design failures, underscoring the implications for economic advancement and security. An algorithm for detecting microcracks on the surface of the pipes with silicate-enamel coatings was developed. The test voltage of the enhanced holiday detector was increased to 40 kV, which allowed the microcracks as small as 1.5 mm long to be detected. A methodology for the remote detection of oil leaks from oil trunk pipelines was presented.

Understanding the optical properties of a restorative material aids in material selection and provides insights into the material’s clinical performance and esthetic longevity. Such knowledge can in turn help clinicians select the best treatment option for their patients. Interpenetrating phase composite materials combine the optical and mechanical properties of ceramics and composite resins; they are often used in direct/indirect restorative options such as inlays, onlays, veneers, single crowns, implant-supported crowns, and short-span fixed partial dentures with esthetically favorable outcomes. The color of a material, which plays an essential role in the esthetic outcome, can change over time depending on different intrinsic and extrinsic factors. Those intrinsic factors include chemical composition, resin-matrix structure, and filler particle sizes; extrinsic factors include surface treatment protocols, the patient’s smoking status, and the consumption of beverages such as coffee, tea, red wine, fruit juice, cola, etc. To fabricate restorations that complement a person’s natural teeth, it is essential to determine the color properties of these materials (e.g., translucence, hue, chroma, and opalescence).</p>","PeriodicalId":579,"journal":{"name":"Glass and Ceramics","volume":"81 5-6","pages":"217 - 224"},"PeriodicalIF":0.6,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142414823","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}
