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.

腐蚀和磨损等表面降解过程具有非常重大的社会、经济和安全影响。这些降解过程影响着许多工业部门，包括运输（船舶和汽车）、航空航天、核能、石油和天然气及其各自的供应链。仅腐蚀一项就给全球工业造成每年 2 万亿美元的损失，其中英国每年损失 550 亿英镑，全球石油和天然气行业每年损失 13.7 亿美元。由此造成的英国经济磨损成本估计为240亿英镑每年约占该国 GDP 的 1.6% 该计划旨在通过利用计算机建模、原子级实验技术、操作成像和表征以及访问以前未开发的现场数据集来解决这个古老的问题。 BP 在研究开发和创新方面投入巨资，并与曼彻斯特大学 (UoM) 建立了长期、成功的合作关系。2012 年，BP 成立了。 BP 国际先进材料中心 (BP-ICAM) 投资 1 亿美元，为期 10 年，旨在解决 BP 核心业务面临的挑战。在 BP 主办的“材料技术展望”研讨会之后，表面降解被确定为未来的一个高度优先领域。研讨会认为，通过利用先进的操作技术和多尺度建模来提出有关基础研究问题，有机会用机械驱动的方法取代工业经验主义。腐蚀皮和摩擦膜的成核和生长，以及如何通过抑制剂、润滑剂和表面涂层和处理来控制它们，这种繁荣伙伴关系将使我们能够补充 BP-ICAM 内进行的应用研究，提出比 BP-ICAM 更基础的表面退化研究问题。此外，ICAM 可以应对这一挑战，需要 ICAM 合作伙伴提供的额外技能，因此将受益于爱丁堡大学和爱丁堡大学在高压环境下材料行为和摩擦腐蚀方面的关键专业知识。防止严苛环境中的表面降解团队将通过多尺度评估研究腐蚀垢和摩擦膜如何引发、生长和分解，确定在非常严苛的环境下抑制或防止降解的方法。该项目将考虑化学和摩擦膜。它通过了解材料表面和近地表（10-100nm）流体环境之间的关键相互作用来研究表面退化的机械效应，它集成了石油和天然气作业中实际条件的先进表面分析研究，以更好地了解退化问题。与最新进展一样及时借助计算建模和成像的力量，研究人员能够跨越长度和时间尺度观察动态系统和“现实世界”条件，最终，实验室中形成的基本理解将与从 BP 到现场的大型数据集相一致。通过这些对表面退化机制的基本见解，该项目将开发可靠的表面退化预测多尺度模型，提出新的材料系统，以防止和预防腐蚀和磨损；工业标准化测试用于退化评估和建议新的缓解策略可延长使用寿命。
