Accelerated Manufacturing with Chrome Free Sacrificial Cermet Coatings in Aerospace (AMSCA)

Previously, sacrificial coatings used for corrosion protection in aerospace contain Cr6+. In compliance with the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) legislation, hexavalent Chromium (Cr6+) must be replaced. Currently available alternatives do not give acceptable performance, so new replacement materials are needed. A complete supply chain consortium, along with academic and CATAPULT support, has come together to address this issue. This ATI-approved project aims to formulate a new sacrificial coating for corrosion protection of steel aero-engine components and demonstrate the technology to technology readiness level (TRL) 5. In addition, improved, cost-effective application methodology will be developed, incorporating automation where appropriate, to increase manufacturing rate and capacity and reduce waste. Furthermore, in a field traditionally developed on an empirical basis, this project aims to provide an improved science based understanding of the coating behaviour, which will underpin the innovative sacrificial coating technology being developed.
