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

欧洲立法(REACH法规)要求在2017年9月之前消除致癌的六价铬(Cr6+)。现有的用于航空航天防腐的牺牲涂层都含有Cr6+，因此必须更换。目前可用的替代材料无法提供可接受的性能，因此需要新的替代材料。一个完整的供应链联盟，加上学术和弹射支持，已经聚集在一起来解决这个问题。本项目旨在研制一种新型的不含六价铬的航空发动机钢质部件腐蚀防护祭祀涂层，并向TRL5进行技术示范。此外，将制定改进的、具有成本效益的应用方法，适当时纳入自动化，以提高制造速度和产能并减少浪费。此外，在一个传统上建立在经验基础上的领域，该项目旨在提供对涂层行为的更好的科学理解，这将为正在开发的创新牺牲涂层技术奠定基础。

European legislation (REACh regulations) requires the elimination of hexavalent Chromium (Cr6+), which is carcinogenic, by September 2017. Existing sacrificial coatings, used for corrosion protection in aerospace, all contain Cr6+ and, therefore, must be replaced. Currently available alternatives do not give acceptable performance, so new replacement materials are needed. A complete supply chain consortium, plus academic and CATAPULT support, has been brought together to address this issue. This project aims to formulate a new sacrificial coating for corrosion protection of steel aero-engine components that is free from hexavalent chromium and demonstrate the technology to TRL5. 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.
