Surface degradation processes, such as corrosion and wear have very significant societal, economic and safety implications. These degradation processes impact a large number of industrial sectors including, transport (marine & automotive), aerospace, nuclear, oil and gas and their respective supply chains. Corrosion alone costs industry globally $2 trillion each year, of which £55 billion per annum is the cost to the UK and $1.37 billion per year the cost to the global Oil & Gas sector. The resulting cost of wear to the UK economy is estimated at £24 billion per annum, approximately 1.6% of the country's GDP. This programme seeks to tackle this age old problem through harnessing advances in computer modelling, experimental techniques at the atomic level, in operando imaging and characterisation and accessing previously untapped in-field data sets to obtain fresh insights into materials surface degradation under the demanding environments in which they operate.BP invest heavily in research development and innovation and have developed a long term, successful collaboration with the University of Manchester (UoM). In 2012, BP founded the BP International Centre for Advanced Materials (BP-ICAM) a $100m, 10 year investment to address challenges across BP's core business. Following a 'Materials Technology Outlook' workshop hosted by BP, surface degradation was identified as a high priority area for future research with the potential for transformational change. The workshop felt there was an opportunity to replace industrial empiricism with mechanistically driven approaches by exploiting advances in-operando techniques and multiscale modelling to ask fundamental research questions about the nucleation and growth of corrosion scales and tribofilms and how to control them through inhibitors, lubricants and surface coatings and treatments. This Prosperity Partnership will enable us to complement the applied research undertaken within BP-ICAM asking more fundamental research questions about surface degradation than BP-ICAM could tackle. Further this challenge requires additional skills beyond those provided by the ICAM partners and so will benefit from key expertise in the behaviour of materials in high pressure environments and tribocorrosion from the Universities of Edinburgh and Leeds respectively.The preventing surface degradation in demanding environments team will look at how both corrosion scales and tribofilms initiate, grow, and breakdown through a multiscale appreciation identify ways to inhibit or prevent degradation under very demanding environments. This project will consider both the chemical and mechanical effects of surface degradation by understanding the key interaction between the material surface and near surface (10-100nm) fluid environment. It integrates advanced surface analysis studies of realistic conditions in oil and gas operations to gain a better understanding of degradation issues. It is timely as recent advances in the power of computational modelling and imaging enable researchers to look across length and time scales and observe dynamic systems and 'real world' conditions. Finally the basic understanding developed in the laboratory will be held up against big in-field data sets from BP to inform and challenge the research.Through these fundamental insights into the mechanisms underlying surface degradation, this programme will; develop reliable predictive multi-scale models of surface degradation; present new materials systems for protection against, and prevention of, corrosion and wear; create new standardised tests for industry to use in the evaluation of degradation and propose new mitigation strategies to extend operational lifetimes.

诸如腐蚀和磨损之类的表面退化过程具有非常重要的社会，经济和安全性。这些退化过程影响了许多工业部门，包括运输（海洋和汽车），航空航天，核，石油和天然气及其各自的供应链。仅腐蚀每年腐蚀行业的成本200万亿美元，其中每年550亿英镑是英国的成本，每年13.7亿美元的成本是全球石油和天然气行业的成本。英国经济造成的磨损成本估计为每年240亿英镑，约占该国GDP的1.6％。该计划旨在通过利用计算机建模的进步，原子能层面的实验技术，在操作数像和表征上的实验技术来解决这个古老的问题，并访问先前未开发的现场数据集，以在苛刻的研究环境中获得对材料表面降级的新见解。BP他们在苛刻的环境下进行了研究，并在研究中进行了大量的研究，并在研究方面进行了研究，并与一项成功的研究进行了培训，并与一项成功的大学进行了培训。 2012年，BP创立了BP国际高级材料中心（BP-ICAM）一项1亿美元，10年的投资，以应对BP核心业务的挑战。遵循BP主持的“材料技术前景”研讨会，将表面退化视为未来研究的高优先级领域，具有变革性变化的潜力。研讨会认为，通过利用进步的前进技术和多尺度建模来替代工业经验主义的机会，询问有关腐蚀量表和互感的成核和生长的基础研究问题，以及如何通过抑制剂，润滑剂和表面涂料和涂层和固定剂来控制它们。这种繁荣伙伴关系将使我们能够完成BP-ICAM中进行的应用研究，询问比BP-ICAM可以解决的有关表面退化的基本研究问题。进一步的挑战还需要超出ICAM合作伙伴提供的其他技能，因此将受益于高压环境中材料行为的关键专家和分别来自爱丁堡大学和利兹大学的互动的材料行为。在苛刻的环境中，团队中的表面退化将如何通过腐蚀量表和差异来构成，并在多种方面进行质疑，并识别多样化的方式，并差异化。环境。该项目将通过了解材料表面与近表面（10-100nm）流体环境之间的关键相互作用来考虑表面降解的化学和机械效应。它整合了对石油和天然气操作中现实状况的高级表面分析研究，以更好地了解降解问题。这是及时的，因为计算建模和成像的力量的最新进展使研究人员能够遍历长度和时间尺度，并观察动态系统和“现实世界”条件。最终，实验室中发展的基本理解将对来自BP的大型现场数据集进行依据，以告知和挑战研究。通过这些基本的见解对表面降低的机制，该计划将；开发可靠的预测性多尺度降解模型；目前可以保护和预防，腐蚀和磨损的新材料系统；为行业创建新的标准化测试，以评估退化和提案的新缓解策略，以延长运营寿命。
