Abstract The use of micron sized nanoporous diatom algae exoskeletons for inhibitor storage and sustained corrosion protection of coated aluminium structures upon damage is presented. In this concept the algae exoskeleton allows local inhibitor loading, limits the interaction between the cerium and the epoxy/amine coating and allows for diffusion-controlled release of the inhibitor when needed. The inhibitor release and corrosion protection by loaded exoskeletons was evaluated by UV/Vis spectrometry, a home-built optical-electrochemical setup, and Raman spectroscopy. Although this concept has been proven for a cerium-epoxy-aluminium alloy system the main underlying principle can be extrapolated to other inhibitor-coating-metal systems.

负载铈的藻类外骨骼用于涂层 AA2024-T3 的主动腐蚀保护

摘要介绍了微米级纳米多孔硅藻外骨骼在涂层铝结构损坏时用于抑制剂储存和持续腐蚀保护的用途。在这个概念中，藻类外骨骼允许局部抑制剂负载，限制铈和环氧树脂/胺涂层之间的相互作用，并允许在需要时扩散控制释放抑制剂。通过紫外/可见光谱、自制的光电化学装置和拉曼光谱评估负载外骨骼的抑制剂释放和腐蚀保护。尽管这一概念已在铈-环氧-铝合金系统中得到证实，但主要的基本原理可以外推到其他抑制剂-涂层-金属系统。
