项目摘要

Coated metal products are of ubiquitous importance to each and every one of us. With the introduction of the Waste Electrical and Electronic Equipment (WEEE) directive in 2004 it is now becoming impossible to use traditional pre-treatments and primers based on hexavalent chromium, which is both toxic and carcinogenic, in electronic goods. Increasingly, as the End of Life Vehicles (ELV) directive comes into full force by 2006, the same will be true in the automotive sector. This critical environmental legislation is being rolled out to other market sectors and will inevitably encompass all metallic products in all sectors including construction materials and aerospace. This makes establishing high performance chromium free coating technologies one of the most important research areas in corrosion. The importance of the work carried out at UWS to this industry sector is clear from the significant levels of government, industry and development agency funding attracted from 2002 to the present time. In order that UK steel manufacturing industry maintains and internationally leading position on coated products chromium free coating development must be combined with novel alloy coatings and coating technologies. This Platform proposal underpins consolidation and growth of the Corrosion and Coatings Research Group at UWS / which has already achieved a world-leading research reputation. Undoubtedly the key strength of the Group lies in the quality and experience of its Research Staff and the Platform Grant (in conjunction with current and anticipated Research Grants) will provide a secure base whereby four of these may be retained in continuous employment over a five year period. This will allow the Group to adopt a more ambitious research strategy and participate in potentially risky and adventurous collaborative programmes with leading university and industry groups world-wide. Core activities will include the development of powerful new combinatorial methodologies for the generation of metal alloy, conducting polymer and ion-exchange ceramic anti-corrosion coating component libraries. Also, the development of high-throughput, parallel, corrosion screening techniques based on scanning electrochemical instrumentation. These will permit the rapid evaluation of individual coating components, identify synergistic interactions between components and provide a wealth of fundamental kinetic and mechanistic information. State-of-the-art electron backscatter diffraction techniques will be also used to obtain a new and fundamental understanding of relationships between microstructure, grain orientation and corrosion resistance in metal and metal-alloy coatings. Scoping studies will include: mechanistic investigations of the interplay between photochemistry and electrochemistry in environmentally driven organic coating degradation, coating deposition using self-assembled conducting-polymer nanofibres, computational modelling of corrosion-driven coating failure, interphase engineering of coatings and investigating the practicality of PVD for metallic coil-coatings on steel. The management infrastructure already in place at UWS will ensure the programme delivers high-quality, technologically-relevant research, new materials and new methodologies which will be widely applicable.

涂层金属产品对我们每个人都无处不在。随着2004年废物电气和电子设备（WEEE）指令的引入，现在不可能在电子商品中使用基于六价铬的传统预处理和底漆，这既有毒又是致癌的。随着寿命末期（ELV）指令的终结越来越多，到2006年，汽车行业也将是正确的。这项关键的环境立法正在向其他市场部门推出，不可避免地涵盖了包括建筑材料和航空航天在内的所有部门中的所有金属产品。这使得建立高性能铬涂料技术是腐蚀中最重要的研究领域之一。从2002年至今，政府，工业和发展机构的资金吸引了大量的政府，工业和发展局资金，在UWS向该行业进行的工作的重要性显然。为了使英国钢制造业在涂层产品上保持和国际领先地位，必须与新颖的合金涂料和涂料技术结合使用。该平台建议基于UWS / UWS腐蚀和涂料研究小组的整合和增长，该小组已经获得了世界领先的研究声誉。毫无疑问，该小组的关键优势在于其研究人员的质量和经验和平台赠款（与当前和预期的研究赠款一起）将提供一个安全的基础，其中其中四个可以在五年内连续就业中保留。这将使该小组能够采用更雄心勃勃的研究策略，并与全球领先的大学和行业团体一起参与潜在的风险和冒险的合作计划。核心活动将包括开发强大的新组合方法，用于产生金属合金，进行聚合物和离子 - 交换陶瓷抗腐蚀涂料组件库。此外，基于扫描电化学仪器的高通量，平行，腐蚀筛选技术的开发。这些将允许对单个涂料组件进行快速评估，确定组件之间的协同相互作用，并提供大量的基本动力学和机械信息。最先进的电子反向散射技术还将用于获得对金属和金属合金涂层中微观结构，晶粒方向和耐腐蚀性之间关系的新的基本理解。 Scoping studies will include: mechanistic investigations of the interplay between photochemistry and electrochemistry in environmentally driven organic coating degradation, coating deposition using self-assembled conducting-polymer nanofibres, computational modelling of corrosion-driven coating failure, interphase engineering of coatings and investigating the practicality of PVD for metallic coil-coatings on steel. UWS已经建立的管理基础架构将确保该计划提供高质量的，技术上的研究，新材料和新方法，这些方法将广泛适用。
