REACH Compliant Hexavalent Chrome Replacement for Corrosion Protection

金属腐蚀和磨损目前每年给全球工业造成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使用含有六价铬(Cr6+)的化合物，用于：铬酸阳极氧化(CAA)、化学转化膜、底漆、油漆和硬铬电镀(EHC)。腐蚀和磨损对防护要求极其苛刻的航空航天工业尤为重要。欧洲REACH立法预计将在2016年前禁止使用含有Cr6+的材料，因为它具有致癌特性。这对航空航天工业来说是一个关键问题，并在2011年国家航空航天技术战略中被强调为优先事项。人们已经做了许多尝试来引入无Cr6+的材料和工艺。解决方案被发现并不像预期的那样强大，部分原因是缺乏经过验证的加速测试方法，导致意外失败。个别航空航天公司正在开发自己的专有解决方案。这造成了供应链上的问题，它发现很难支持这一点。此次竞标通过汇集从中小企业到学术界的综合航空航天团队来解决这一问题，以确定创新的解决方案，并开发可靠的加速测试方法，准确地再现严重的环境应用。这将使该部门能够采取共同的

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
