The joining of different light metals through friction stir welding (FSW) is gaining interest as a method to decrease weight and improve fuel efficiency. However, to ensure durability, these welded metals may require surface treatments to protect against corrosion or wear. This study presents a novel approach for the simultaneous delivery of two distinct corrosion inhibitors to Ti-Mg dissimilar PEO treated joints on demand. The research focuses on the synthesis, characterization, and application of cerium@polystyrene (Ce@PS) nanocontainers, which are loaded with 8-hydroxyquinoline (8-HQ) to enhance corrosion protection. The synthesis involves several key steps, including the formation of a cerium-based outer layer around polystyrene nanospheres, the selective removal of the polystyrene core to create a porous structure, and the subsequent loading of the 8-HQ inhibitor. Structural and compositional analyses, conducted using scanning transmission electron microscopy (STEM) and energy-dispersive X-ray spectroscopy (EDS), confirmed the successful incorporation of 8-HQ within the nanocontainers. Additionally, Fourier-transform infrared spectroscopy (FTIR) provided detailed information about the chemical composition of the organic materials throughout the synthesis process. Thermal decomposition analysis verified the successful fabrication and stability of the dual-shell nanocontainers.

通过搅拌摩擦焊 （FSW） 连接不同的轻金属作为一种减轻重量和提高燃油效率的方法越来越受到关注。但是，为了确保耐用性，这些焊接金属可能需要进行表面处理以防止腐蚀或磨损。本研究提出了一种按需将两种不同的缓蚀剂同时输送到 Ti-Mg 不同 PEO 处理的接头的新方法。研究重点是 cerium@polystyrene （Ce@PS） 纳米容器的合成、表征和应用，这些容器装载有 8-羟基喹啉 （8-HQ） 以增强防腐蚀保护。合成涉及几个关键步骤，包括在聚苯乙烯纳米球周围形成铈基外层，选择性去除聚苯乙烯核以形成多孔结构，以及随后加载 8-HQ 抑制剂。使用扫描透射电子显微镜 （STEM） 和能量色散 X 射线光谱 （EDS） 进行的结构和成分分析证实了 8-HQ 成功掺入纳米容器中。此外，傅里叶变换红外光谱 （FTIR） 提供了有关整个合成过程中有机材料化学成分的详细信息。热分解分析验证了双壳纳米容器的成功制造和稳定性。
