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.

这个令人兴奋的博士项目将新型成像技术的应用与产品存储基础设施和暴露环境相关的腐蚀过程的表面化学表征相结合。这里的主要目标是首先优化现有的表面分析程序，以更好地了解环境参数对腐蚀行为的影响，其次是发展机械理解，以评估表面化学如何影响材料寿命。同样的方法将被应用于测试一系列拟议的腐蚀缓解策略，以及探索材料的电化学响应受到大气干湿循环。表面成像和各种形式的表征将导致创建一套多尺度分析技术，以检测和量化从微观到宏观尺度的腐蚀。后者旨在发展店内腐蚀监测能力。数据的采集，结合拟议的分析程序，将是他们的第一套工具，以检测-与信心-最早的时间间隔，在此时间间隔内，可以在所有成像技术中稳健地检测到腐蚀产物。所开发的方法将适用于铝合金6063和316L型不锈钢。
