Nickel Superalloy Design for Corrosion Resistance

我的奖学金将领导一个研究项目，采用最先进的实验和计算技术，为镍高温合金和钢的环境退化提供新的、基本的见解，这些退化是由于它们在使用中遇到的腐蚀性气体相互作用造成的。我已经发表了我的腐蚀和氧化研究计划的一些初步工作，尽管开发耐腐蚀高温材料的全部潜在好处几乎没有被探索过。我计划通过在实验室熔炉中暴露于腐蚀性环境中的样品的高级特性，在高温机械测试期间以及对我的工业合作者提供的退役部件的研究来解决这些问题。研究结果将用于设计新一代合金，其耐腐蚀性将根据其特定应用而定制。为了使我的研究产生最大的影响，我将与我的工业合作者，如罗尔斯·罗伊斯公司，以及我的学术合作者，包括迈克尔·穆迪教授（牛津大学原子探针断层摄影组）密切合作，对样品进行表征，为合金设计提供信息，并生产具有更好耐腐蚀性的新型高温合金。腐蚀研究是非常及时的，具有全球重要性，具有潜在的未来节省和延长组件寿命的潜力。

My fellowship will lead a research programme employing state of the art experimental and computational techniques to provide new, fundamental insight into the environmental degradation of nickel superalloys and steels that occur as a result of interactions with the corrosive gaseous species they encounter in-service. I have published some preliminary work from my corrosion and oxidation research program, though the full potential benefits for the development of corrosion resistant high temperature materials, have barely been explored. I plan to address these questions through advanced characterisation of samples exposed to corrosive environments in laboratory furnaces, during high temperature mechanical tests and a study of ex-service components provided by my industrial collaborators. The results will then be used to design a new generation of alloys, whose corrosion resistance will be tailored to their specific applications. To maximise the impact of my research, I will work closely with my industrial collaborators such as Rolls-Royce plc, as well as my academic collaborators, including Prof Michael Moody (Atom probe Tomography Group, University of Oxford), to characterise the samples, inform alloy design and produce new superalloys with improved corrosion resistance. Corrosion research is extremely timely and globally important with potential for substantial future savings and component lifetime extension.
