"Hard chrome plating is widespread through many industrial sectors due to its excellent combination of hardness and low friction combined with corrosion and wear resistance. The manufacturing process however requires the use of hazardous chromium salts which give rise to health and environmental concerns, leading to an uncertain long-term future due to legislative changes such as REACH.Electrodeposited metal matrix nanocomposites (MMNCs) have the potential to make a significant improvement to surface properties such as increased microhardness and inherent lubricity. The development of nanotechnology over the last 25 years means that there are now a multitude of nanoparticles, nanowires and nano-tubes in a wide range materials, hence the scope for new nanocomposite coatings is greater than ever. Recent work at Leicester University has resulted in demonstration of the process across a range of coating compositions.This enables the production of strengthened coatings, with the potential to develop a coating with functional performance equivalent to hard chrome.Working as a consortium, the present project is taking the work forward to validate the capability with partners JCB, PPUK, NMB Minebea and Weir Valves and Controls for a wide range of industrial applications. Additionally, the technology will be made more broadly available through Tewkesbury Diamond Chrome Plating which provides electroplating services to industry, and through TWI with its network of over 700 industrial members."

“硬Chrome镀层广泛应用于许多工业部门，因为它具有优异的硬度和低摩擦力以及耐腐蚀性和耐磨性。然而，制造过程需要使用有害的铬盐，这会引起健康和环境问题，导致不确定的长期未来，由于立法的变化，如REACH。电沉积金属基纳米复合材料（MMNC）有可能使表面性能，如增加显微硬度和固有的润滑性显着改善。纳米技术在过去25年的发展意味着现在有大量的纳米颗粒，纳米线和纳米管在广泛的材料，因此新的纳米复合材料涂层的范围比以往任何时候都大。莱斯特大学最近的工作已经在一系列涂料组合物中展示了该工艺。这使得能够生产强化涂层，并有可能开发出功能性能与硬Chrome相当的涂层。作为一个财团，本项目正在与合作伙伴JCB，PPUK，NMB Minebea和Weir阀门和控制器适用于广泛的工业应用。此外，该技术将通过为工业提供电镀服务的图克斯伯里钻石Chrome电镀公司和拥有700多个工业成员的TWI网络更广泛地提供。"
