However, optimizing the cold spray process for metallizing thermoplastic polymers is a complex task due to the numerous interacting parameters that influence coating quality. As traditional trial-and-error approaches are time-consuming and costly, machine learning (ML) could offer a solution to these challenges by providing further insights into the process and enabling more efficient optimization. The aim of this work is to identify the most relevant input parameters for ML models, with a particular focus on powder characteristics, to predict two critical outcomes: particle flattening and penetration depth. Two distinct datasets were created for this study: one focused on particle yield strength and the other on powder density, each combined with further input parameters like impact velocity and substrate yield strength. These datasets were constructed using experimental data and finite element modeling (FEM) simulations, with materials including copper, aluminum, titanium, and others, applied to thermoplastic substrates like polyether ether ketone (PEEK), acrylonitrile butadiene styrene (ABS), and polyamide 66 (PA66). Several ML algorithms, including decision trees, neural networks, and Gaussian process regression, were tested to predict coating behavior, and the effects of Z-score normalization were evaluated for improving model stability and prediction accuracy. The results show that particle yield strength is crucial for flattening, while particle density primarily governs penetration depth. This study demonstrates that ML, when combined with a solid understanding of the process, offers an effective framework for optimizing CS deposition on polymers.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 8","pages":"6527 - 6538"},"PeriodicalIF":2.2,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-025-11096-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To optimize their performance in high-demand environments, surface functionalization of vitrimers and vitrimeric composites is crucial to enhance their durability and reliability in harsh conditions. This research work aims at studying the feasibility of metallising vitrimer-based components through cold spray technology. Aluminium coatings were applied under varying process parameters, inlet gas temperature (<i>T</i> = 150 –450 °C) and standoff distance (SoD = 70 mm–100 mm), to evaluate their impact on deposition quality and substrate behaviour. The deposition processes were performed on non-reinforced vitrimeric substrates as well as on vitrimeric matrix substrates reinforced with carbon fibre fabric. The results suggest that successful metallization occurs when the substrate temperature exceeds the topology freezing transition temperature (Tv ≈ 170 °C), enabling the ductile behaviour necessary for effective adhesion. At <i>T</i> = 300 °C and SoD = 100 mm, pure vitrimer coatings exhibited an average thickness of 50 ± 10 µm with minimal substrate deformation (grooves &lt; 4% of panel thickness), while lower temperatures (<i>T</i> = 150 °C) resulted in brittle fracture and poor adhesion. Surface roughness increased from Sa = 0.15 ± 0.05 µm for uncoated substrates to Sa = 6.59 µm after coating. In contrast, composite substrates demonstrated enhanced stability due to fibre reinforcement, which constrained excessive substrate flow. At the best process conditions (<i>T</i> = 300 °C and SoD = 100 mm), composite panels achieved homogeneous coatings with Sa = 4.513 µm. However, excessive temperatures (<i>T</i> = 450 °C) led to substrate erosion and fibre damage in both pure vitrimer and composite panels.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 8","pages":"6510 - 6526"},"PeriodicalIF":2.2,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-025-11108-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144117758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the relationship between the microporous structure of sintered nanosilver materials and their macroscopic mechanical properties has not been fully explored. In this study, load–displacement curves of porous sintered nanosilver materials were obtained through indentation experiments. Finite element simulation was then applied to sintered nanosilver materials with different porosities to understand the impact of porosity on their mechanical properties. Using a two-dimensional axisymmetric indentation model based on the finite element method, sintered nanosilver with a porosity of 10% was indented to a depth of 10 <span>(upmu)</span>m. The sintered nanosilver matrix model had dimensions of 0.25 mm × 0.25 mm. Simulations were carried out on sintered nanosilver with porosities of 10, 20, 25, and 30%. Indentation curves and stress–strain curves were obtained for each porosity. The mechanical properties of the materials, such as Young’s modulus and yield strength, were analyzed using indentation curves. The results show that the Young’s modulus and yield strength gradually decrease with increasing porosity of the sintered nanosilver material. This study has successfully explained the correlation between the elastoplastic mechanical properties and the indentation response of sintered nanosilver materials with different porosities. In addition, this paper discusses the relationship between the mechanical properties and porous structure of sintered nanosilver materials in detail, providing a more comprehensive experimental basis and theoretical support for research and practical application in high-power electronic devices.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 6","pages":"4564 - 4572"},"PeriodicalIF":2.2,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143845681","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}
