Hexavalent chromates set the benchmark for corrosion protection for a number of industries and they areessential for the safety of current Aerospace products. However, EU REACH legislation has tightly restricted thesale and use of these chemical substances which creates a business continuity threat to the UK and EEA supplychains. One key technology is chromate conversion coatings (CCC) that are essential for the protection ofaluminium components. While there are a number of proposed alternatives on the market, previous work hasidentified these to be unsuitable.A consortium has been brought together in order to develop and industrialise CCC alternatives to ensure thatthey meet stringent requirements set by the Aerospace industry. The lifetimes of these hex-chrometechnologies will be measured using advanced methodology so that they can be safely introduced intoAerospace products. Furthermore, the new technologies will be available for the entire UK supply chain to use,including for other industries such as medical, automotive, oil and gas.

六价铬酸盐为许多行业的防腐设定了基准，它们对当前航空航天产品的安全至关重要。然而，欧盟REACH立法严格限制了这些化学物质的销售和使用，这对英国和EEA供应链造成了业务连续性威胁。一项关键技术是铬酸盐转化涂层(CCC)，它对铝部件的保护至关重要。虽然市场上有许多拟议的替代品，但之前的工作发现这些替代品是不合适的。一个联合体已经成立，以开发和工业化CCC替代品，以确保它们满足航空航天行业设定的严格要求。这些六色技术的寿命将使用先进的方法进行测量，以便它们可以安全地引入航空航天产品。此外，新技术将可供整个英国供应链使用，包括医疗、汽车、石油和天然气等其他行业。
