这个小型企业创新研究第二阶段项目专注于开发纳米晶软铁磁材料，用于各种终端应用，如电磁干扰(EMI)抑制、磁轴承和电感。第一阶段清楚地确定了通过专利微波等离子体技术生产这些材料的可行性。此外，这些纳米材料使用专利的等离子体压力压实技术被固结到接近理论密度，压实件显示出高磁强和低矫顽力。在第二阶段，这一过程将是为具体应用开发这些材料。我们的工业合作伙伴将对生产的材料进行评估，以评估参数，这些参数对于将技术转变为立即有用的产品至关重要。此外，还将支持知识产权保护和将该技术商业化的各种途径。具有优异磁性能和机械性能以及低铁损的纳米晶软磁材料有许多应用。这包括EMI预防组件、发电机、变压器、数据通信接口组件、磁轴承(旋转机械领域的商业高性能应用)、磁记录头、电机、传感器和电抗器。MMI计划专注于三个细分市场，包括(1)电磁干扰抑制(2)磁轴承和(3)电感。

This Small Business Innovation Research Phase II project focuses on developing nanocrystalline soft ferromagnetic materials for various end use applications such as Electromagnetic Interference (EMI) suppression, magnetic bearings and inductors. Phase I clearly established the feasibility of producing these materials via a patented microwave plasma technique. In addition, these nanomaterials were consolidated to near theoretical densities using a patented plasma pressure compaction technique and the compacts exhibited high magnetic strength and low coercivity. During Phase II, the process will be to develop these materials for specific applications. Our Industrial partners will evaluate the produced materials to evaluate parameters, which are critical for transitioning the technology to an immediate useful product. In addition, an IP protection and various avenues to commercialize thetechnology will be sought.There are numerous applications for nanocrystalline soft magnetic materials with superior magnetic and mechanical properties and low core loss. This includes EMI prevention components, generators, transformers, data communication interface component, magnetic bearings (commercial high-performance applications in the domain of rotating machinery), magnetic recording heads, motors, sensors, and reactors. MMI plans to focus on three market segments including (1) EMI suppression (2) Magnetic Bearings and (3) Inductors.
