Cold spray is a new technology to restore in-service wear/corrosion damage on high-value aluminium, magnesium and titanium aerospace parts that are unrepairable by other means. Repair has technical, cost and environmental benefits, but the UK is lagging behind in adopting the technology. In the US and Australia over 200 military aircraft repairs have been developed and hundreds of commercial aviation repairs approved, saving taxpayers and the aviation industry at least $100m so far. Existing repairs are dimensional, but load-bearing repairs are now also being developed. This requires special heat treated metal powders, because in cold spray, powder impacts a surface at supersonic speeds and bonds to it via a mechanism similar to explosion welding. There is no melting, so the powder structure is transferred directly to the coating. Research into these powders has just started in the USA and many technical challenges remain. The powders must be further developed and proven, and a reliable commercial supply established. In this project, the UK has the chance to establish a global lead in engineered powders for cold spray. With InnovateUK investment PSI Ltd. (an SME) will take advantage of its 30 years’ experience in powders to position itself as a global supplier of advanced cold spray powders. To this end, PSI is partnering with BAE Systems and TWI. TWI owns the only independent state-of-the-art cold spray facility in Europe, and has been active in cold spray since 2006. BAE Systems estimate the project outcomes could save the UK taxpayer >£100m pa after 8 years. SME project partner Alphatek Hyperformance Coatings Ltd is considering investing in cold spray, with a view to commercialising aircraft component repairs for existing and new clients.

冷喷涂是一种新技术，用于修复高价值铝、镁和钛航空航天部件的使用中磨损/腐蚀损坏，这些部件无法通过其他方式修复。维修具有技术、成本和环境效益，但英国在采用该技术方面落后。在美国和澳大利亚，已经开发了200多架军用飞机的维修项目，数百架商用飞机的维修项目获得批准，到目前为止，为纳税人和航空业节省了至少1亿美元。现有的修复是尺寸性的，但现在也正在开发承重修复。这需要经过特殊热处理的金属粉末，因为在冷喷涂中，粉末以超音速撞击表面并通过类似于爆炸焊接的机制与表面结合。没有熔化，因此粉末结构直接转移到涂层上。在美国，对这些粉末的研究刚刚开始，仍然存在许多技术挑战。必须进一步开发和验证粉末，并建立可靠的商业供应。在这个项目中，英国有机会在冷喷涂工程粉末领域建立全球领先地位。随着InnovateUK的投资，PSI有限公司（一家中小型企业）将利用其30年的粉末经验，将自己定位为先进的冷喷涂粉末的全球供应商。为此，PSI正在与BAE系统公司和TWI合作。TWI拥有欧洲唯一独立的最先进的冷喷涂设施，自2006年以来一直活跃在冷喷涂领域。BAE系统公司估计，8年后，该项目的成果可以为英国纳税人每年节省超过1亿英镑。中小企业项目合作伙伴Alphatek Hyperperformance Coatings Ltd正在考虑投资冷喷涂，以期为现有和新客户实现飞机部件维修的商业化。
