Hexavalent chromates set the benchmark for corrosion protection for a number of industries and they are essential for the safety of current Aerospace products. However, EU REACH legislation has tightly restricted the sale and use of these chemical substances which creates a business continuity threat to the UK and EEA supply chains. One key technology is chromate conversion coatings (CCC) that are essential for the protection of aluminium components. While there are a number of proposed alternatives on the market, previous work has identified these to be unsuitable. A consortium has been brought together in order to develop and industrialise CCC alternatives to ensure that they meet stringent requirements set by the Aerospace industry. The lifetimes of these hex-chrome technologies will be measured using advanced methodology so that they can be safely introduced into Aerospace 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.
