Abstract

This study investigates time lags between environmental changes, electrolyte formation, and atmospheric corrosion sensor responses under controlled multi-droplet wetting. A commercial corrosion and environmental sensor was combined with in-situ microscopy, and an Artificial Intelligence (AI)-based segmentation approach was applied to track droplet growth. A cross-correlation analysis identified and quantified time lags between Surface Relative Humidity (SRH), droplet radius, and sensor responses based on Interdigitated Electrodes (IDE) measuring conductance, galvanic corrosion, and free corrosion. This approach ultimately aids in understanding how environmental fluctuations affect the dynamic behaviour of the electrolyte layer and, in turn, influence atmospheric corrosion sensor responses.

在监测的多液滴润湿过程中，腐蚀和环境传感器的响应延迟：大气腐蚀中的解开时间滞后

本研究研究了受控多液滴润湿下环境变化、电解质形成和大气腐蚀传感器响应之间的时间滞后。将商用腐蚀和环境传感器与原位显微镜相结合，并采用基于人工智能（AI）的分割方法来跟踪液滴的生长。相互关联分析确定并量化了表面相对湿度（SRH）、液滴半径和基于交叉电极（IDE）测量电导、电偶腐蚀和自由腐蚀的传感器响应之间的时间滞后。这种方法最终有助于理解环境波动如何影响电解质层的动态行为，进而影响大气腐蚀传感器的响应。
