This study investigates the correlations between built-up angle, surface fractal complexity, and wettability in additively manufactured surfaces using Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS), and Multi Jet Printing (MJT). Surface topography was measured using four optical techniques: focus variation, confocal microscopy, confocal fusion, and interferometry, across multiple scales. The study explored linear, logarithmic, and exponential regression models to identify the best correlations and scale of interactions between the built-up angle, surface complexity, and contact angle. It was found that the built-up angle significantly influences surface fractal complexity, with strong correlations (R² &gt; 0.85) observed particularly at a scale of around 1100 µm². Confocal fusion offered the best reproducibility of measurements, especially at finer scales (&lt; 100 µm²). Surface complexity was also found to correlate strongly with wettability, especially at scales around 1000 µm² and under 10 µm², where exponential regression models performed slightly better, particularly for MJT surfaces. Topographic measurement modes are reproducible with slightly better correlation indices for confocal fusion, between built-up angle and surface complexity. The best correlation of built-up angle, surface complexity and contact angle parameters was obtained for linear regression. The results suggest that surface wettability can be controlled by adjusting the built-up angle, with FDM and SLS surfaces transitioning from hydrophobic to hydrophilic as the angle increases beyond 70 degree, while MJT surfaces remained hydrophobic even at higher angles. The built-up angle parameter allows modeling wettability in the range of 80–120°. The study also indicates the superiority of multiscale parameters over conventional topographic characterization methods in describing additively manufactured surfaces.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"202 ","pages":"Article 110394"},"PeriodicalIF":6.1,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142660687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To understand the tribocorrosion phenomena induced during the cleaning routine, tribological and tribocorrosion tests were carried out using three inexpensive, eco-friendly domestic cleaning solutions: 8 % acetic acid, and 5 % sodium hydrogen carbonate. Some tests were conducted in demineralized water, which served as a reference medium. High friction and wear were observed with AISI 316 L stainless steel in vinegar and water, consistent with current observations in food cleaning processes. However, in sodium hydrogen carbonate, an unprecedented tribological behavior was recorded under specific test conditions. Worn surface analysis results indicate that this phenomenon is associated with the formation of a passive film composed of chromium oxides/hydroxides and iron oxides/hydroxides, with the emergence of a nickel-rich sublayer. The electrical activity of the passive film demonstrated its insulating behavior. Due to the synergistic interactions between the mechanical wear of the passive film and chemical reactions of AISI 316L stainless steel in sodium hydrogen carbonate, significant improvement in the frictional properties of AISI 316L has been found, which can play an important role in increasing the mechanical life of equipment and energy efficiency.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"202 ","pages":"Article 110382"},"PeriodicalIF":6.1,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142703595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An increase in the V content causes precipitation of the Laves phase (VAl₂) in the body-centered cubic (BCC) matrix. This structural transition increases the alloy hardness and compressive strength through solid solution strengthening, precipitation strengthening and grain refinement strengthening. When x is increased from 0.25 to 1, the maximum compressive strength increases from about 2476 to 3241 MPa at room temperature and from about 521 to 797 MPa at 700 °C, respectively. In-situ oxidation investigation reveals that a higher V content accelerates the oxidation and provides a direct evidence of vanadium oxides melting at 700 °C and thus forming the liquid oxide phases on the surface of HEAs. During high temperature tribological contact, the liquid oxide phases minimize the friction, allowing thicker and more complex oxide layers to form on the worn surface to improve the HEAs’ wear resistance.
