In-situ Imaging and Chemistry Mapping of Corrosion Processes in Product Store Environment

这一令人兴奋的博士项目将新型成像技术的应用与与产品存储基础设施和曝光环境相关的腐蚀过程的表面化学特征相结合。这里的主要目标是首先优化现有的表面分析程序，以便更好地了解环境参数对腐蚀行为的影响，然后发展一种机械理解，以评估表面化学如何影响材料的使用寿命。同样的方法将被用来测试一些建议的缓蚀策略，以及探索材料在大气干湿循环下的电化学响应。各种形式的表面成像和特征将导致一套多尺度分析技术的产生，以检测和量化从微观到宏观的腐蚀。后者旨在发展店内腐蚀监测能力。数据的获取，再加上拟议的分析程序，将是一套首创的工具，可以在所有成像技术中可靠地检测到腐蚀产物的最早时间间隔。该方法适用于6063铝合金和316L不锈钢。

This exciting PhD project combines the application of novel imaging techniques with the characterisation of surface chemistry of corrosion processes relevant to product store infrastructure and exposure environments. Key aim here is to first optimise existing surface analysis routines, to provide a better understanding of the effect of environmental parameters on the corrosion behaviour, followed by the development of a mechanistic understanding to assess how surface chemistry can affect material life-time. The same methodology will be be applied to test a numbere of proposed corrosion mitigation strategies, as well as exploring the electrochemical response of materials subjected to atmospheric wet-dry cycles. Surface imaging and characterisaiton of a wide range of modalities will result in the creation of a set of multiscale analysis techniques to detect and quantify corrosion from the microscopic to macroscopic scale. The latter aims to develop in-store corrosion monitoring capability. The acquisition of the data, combined with the proposed analysis routines, will be a first-of- their-kind suite of tools to detect - with confidence - the earliest interval at which corrosion products can be robustly detected in all imaging technologies. The developed mtethodology will be applied to both aluminium alloy 6063 and type 316L stainless steel.
