Designing and Evaluating Corrosion Sensing Coatings for Marine Environments
收藏资源简介：
Photographic data sets from the result of various environmental exposures of various corrosion sensing coating samples. The sample combinations are PhPh & epoxy on steel, TB & epoxy on steel, PhPh & epoxy on TSZA coated steel, TB & epoxy on TSZA coated steel, PhPh & polyester on steel, TB & polyester on steel, PhPh & polyester on TSZA coated steel, and TB & polyester on TSZA coated steel. The environmental exposures included, laboratory immersion, salt spray cabinet, offshore, and onshore coastal. The hypothesis of the research was two fold. Firstly it was thought that corrosion sensing coatings would detect corrosion in all the above defined environmental exposures. And secondly that their would be a reduction in the corrosion protection of the corrosion sensing coatings in comparison to control samples as assessed by a rust assessment (BS EN ISO 4628-3:2016). The results demonstrated some corrosion sensing for all polymer/dye/substrate/environment combinations with the exception of PhPh & polyester on TSZA which did not sense in any environment. Rust assessment of the results demonstrated little difference in corrosions protection performance between the corrosion sensing coatings and requisit control coatings in any environment.
本数据集源自多款腐蚀传感涂层样品经不同环境暴露试验后的成像结果。样品组合包括：钢基材上的PhPh与环氧树脂体系、钢基材上的TB与环氧树脂体系、TSZA涂层钢基材上的PhPh与环氧树脂体系、TSZA涂层钢基材上的TB与环氧树脂体系、钢基材上的PhPh与聚酯体系、钢基材上的TB与聚酯体系、TSZA涂层钢基材上的PhPh与聚酯体系，以及TSZA涂层钢基材上的TB与聚酯体系。本次试验涉及的环境暴露场景包括：实验室浸泡、盐雾箱试验、近海环境以及近岸陆上环境。本研究提出双重假设：其一，腐蚀传感涂层可在上述所有定义的环境暴露场景中检测到腐蚀现象；其二，参照BS EN ISO 4628-3:2016标准进行锈蚀评级后，相较于对照组样品，腐蚀传感涂层的防腐蚀性能会出现下降。试验结果显示，除TSZA涂层钢基材上的PhPh与聚酯体系在所有环境中均未检测到腐蚀信号外，其余所有聚合物/染料/基材/环境组合均表现出一定的腐蚀传感能力。锈蚀评级结果表明，在任意环境下，腐蚀传感涂层与对应对照组涂层的防腐蚀性能差异极小。
