General Information
With the use of light alloys, such as aluminium and magnesium, new applications have been found to quickly improve existing designs in the aircraft industry. The disadvantage of using these materials is that they are particularly susceptible to corrosion. Environmental degradation is a limiting factor for magnesium–aluminium (Mg–Al) alloys in outdoor applications. An effective way to protect alloys from fast degradation or reduce to the degradation rate is surface treatment. Hexavalent chromium has served as the primary means of corrosion protection in the aircraft industry since 1936 and allowed for the distinctive bare-metal finishes of the World War II era. Hexavalent chromium is a known carcinogen, with the major route of exposure through inhalation of vapour or dust. The chromates are among the current chemicals for which industrial users must find substitutes, or request authorisation from EU regulators to continue their use. In the case of chromium trioxide and the acids, the application deadline was March 2016 and the “sunset” date for the substances is September 2017. Therefore, there is an urgent need facing the aerospace industry to replace the conventional corrosion inhibitor, hexavalent chromium. Regulatory and market drivers are motivating a global effort in the aerospace industry to replace hexavalent chromium-containing materials with hexavalent chromium-free alternatives for various applications.
The ALMAGIC project is focused on solving the aforementioned problematic by validating the developed innovative alternatives to chromium (VI) coatings for aluminium and magnesium alloys. ALMAGIC will ensure the developed solutions comply with the REACH regulations, while all quality standards are met. The project is co-funded by the Clean Sky 2 Joint Technology Initiative (CS2 JTI) which is a Public-Private Partnership between the European Commission and industry.
