This Small Business Innovation Research Phase I project will develop an innovative approach to synthesize anisotropic magnet powder coated with Fe nanoparticles for high performance nanocomposite magnets. The approach for this project lies in converting the Fe nanoparticle synthesis into a deposition process. Fe nanoparticles will be deposited onto anisotropic hard magnetic powders that act as a substrate. Unlike previously employed techniques, the approach this project will take will allow the control of the size of the soft magnetic Fe-particles to the nanoscale. Moreover, it is compatible with mass production. The broader impact/commercial potential from this technology (if successful) would be Fe-nanoparticle coated precursor powder, subsequently consolidated, will lead to a new generation of high performance anisotropic permanent magnets with a maximum energy product, much higher than that of current commercial magnets. This will directly result in the improvement of the functionality of electromagnetic devices and eventually lead to new applications not possible with current permanent magnets.

这个小企业创新研究第一阶段项目将开发一种创新的方法来合成涂有铁纳米粒子的各向异性磁铁粉末，用于高性能纳米复合磁铁。该项目的方法在于将铁纳米颗粒的合成转化为沉积过程。铁纳米颗粒将沉积在作为衬底的各向异性硬磁粉末上。与以前使用的技术不同，该项目将采用的方法将允许将软磁铁颗粒的尺寸控制到纳米级。此外，它与大规模生产兼容。这项技术的更广泛的影响/商业潜力（如果成功）将是铁纳米颗粒涂层前驱体粉末，随后固化，将导致新一代高性能各向异性永磁体的最大能量产品，远远高于目前的商业磁体。这将直接导致电磁器件功能的改进，并最终导致当前永磁体无法实现的新应用。
