REACH Compliant Hexavalent Chrome Replacement for Corrosion Protection

目前，全球金属腐蚀和磨损每年给工业造成1.5-2万亿美元的损失。许多缓解这些问题的系统的基础是利用含有六价铬（Cr6+）的化合物，用于：铬酸阳极氧化（CAA）；化学转化涂料；引物;镀硬铬（EHC）。腐蚀和磨损对于保护要求极其严格的航空航天工业尤为重要。由于Cr6+的致癌性，欧洲REACH法规预计将在2016年禁止使用含Cr6+的材料。这是航空航天工业的一个关键问题，并在2011年国家航空航天技术战略中被强调为优先事项。许多人尝试引入不含Cr6+的材料和工艺。人们发现，解决方案并不像预期的那样健壮，部分原因是缺乏经过验证的加速测试方法，导致了意想不到的失败。个别航空航天公司正在开发自己的专有解决方案。这导致了供应链问题，它发现很难支持。此次竞标通过将中小企业和学术界的综合航空航天团队聚集在一起，确定创新的解决方案，并开发强大的加速测试方法，以准确地再现恶劣环境应用。这将使该部门能够采用共同的

Metal corrosion and wear currently costs industry $1.5-2 trillion globally per annum. The basis of many systems to mitigatethese problems utilise compounds containing hexavalent chromium (Cr6+) as used in: chromic acid anodising (CAA);chemical conversion coatings; primers; paint, and hard chrome plating (EHC). Corrosion and wear are of particularimportance to the aerospace industry where protection requirements are extremely severe. European REACH legislation isexpected to ban the use of Cr6+ containing materials by 2016 due to its carcinogenic properties. This is a critical issue forthe aerospace industry and has been highlighted as a priority in the 2011 National Aerospace Technology Strategy. Anumber of attempts have been made to introduce Cr6+ free materials and processes. The solutions have been found not tobe as robust as expected, due in part, to the lack of validated, accelerated testing methods, resulting in unexpectedfailures. Individual aerospace companies are developing their own, proprietary solutions. This has caused problems in thesupply chain, which it is finding difficult to support. This bid addresses this situation by bringing together an integratedaerospace based team from SMEs to academia to identify innovative solutions and develop robust accelerated testingmethods that accurately reproduce severe environmental applications. This will enable the sector to adopt a common
