The fluid resistance control and corrosion resistance of underwater vehicles are essential indexes for evaluating the performance of underwater vehicles in particular marine environments and harsh conditions. The 7075 aluminum alloy, widely used in spacecraft shells, was selected as the material. We prepared a drag-reduction and robust surface based on shark skin by laser-ablation and plasma electrolytic oxidation. Then, the surface free energy was further modified by chemical modification. The ceramic coating exhibited superhydrophobicity with a water contact angle of 155.6° and roll-off angle (RA) of 5.5°. Compared with Bare Al, the corrosion current density of the superhydrophobic ceramic coating was reduced by 4 orders of magnitude since ZnO-NPs could notably enhance the corrosion resistance of Al alloys. Moreover, due to the protective effect of the ceramic coating and microstructure, the superhydrophobic coating exhibited excellent mechanical durability. Based on numerical simulation, the drag reduction effect of biomimetic microstructure under different Reynolds numbers was investigated. The experimental results indicated that biomimetic microstructure demonstrated notable drag reduction capabilities compared to smooth surfaces, stabilizing at approximately 28% during laminar flow states. Thus, applying this coating method to the underwater vehicle shell was expected to reduce the fluid resistance and extend the operational lifespan in the marine corrosive environment.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 20","pages":"23435 - 23451"},"PeriodicalIF":2.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284391","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}

At first, a simulation of the winding process was conducted to define the component layers, and then a FEM analysis was performed to identify the optimal layering of the tubular structure to support the defined loads. Subsequently, environmental and economic impacts were evaluated by means of life cycle assessment and life cycle costing methodologies. The comparison between the CFRP tubular structure and traditional aluminum alternative was conducted to identify the most sustainable solution. The analysis showed that the CFRP tubular component resulted in lower environmental impacts than the traditional alternative (i.e., about 70% lower considering the whole life cycle) mainly due to the reduced weight. However, the cost evaluation identified the CFRP alternative as the most expensive solution, with production cost 40% higher than the aluminum alternative.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 15","pages":"15324 - 15335"},"PeriodicalIF":2.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-025-11009-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832093","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}

Nonetheless, the ability to precisely manipulate the lamellar structure at the microscale is constrained by current methodologies, thereby impeding the attainment of an optimal balance between strength and ductility. In this study, a copper lamellar structure featuring distinct interlamellar interfaces between alternating coarse- and fine-grained layers was fabricated using friction-assisted electrodeposition (FAED) with alternating current densities. FAED effectively inhibited the epitaxial growth of crystals and promoted stable nucleation across the deposited surface, thereby facilitating rapid transformation of grain size at the microscale. This process resulted in the formation of a distinct interlamellar interface between coarse- and fine-grain layers. The pronounced interlamellar interfaces generated significant back stress, enhancing the strength of the copper (Cu) lamellar structure during deformation. Concurrently, the presence of slip bands traversing multiple layers, along with grain rotations, contributed to exceptional elongation within the Cu lamellar structure, thereby overcoming the conventional strength–ductility trade-off. Consequently, the Cu lamellar structure demonstrated an extraordinary synergy between high strength (484 MPa) and superior ductility (20.9%).
