High-coercivity NdFeB Printed Magnets With Laser Powder Bed Fusion Method
Abstract
NdFeB permanent magnets are key components for the energy transition and the electrification of transportation, which causes their demand to grow at high pace. Yet, the supply risk for rare earth metals motivates the industry to look for an efficient use of magnets. Designing systems with complex-shaped magnets can help reducing the magnet use if accompanied by the development of net-shape processes. Powder Bed Fusion using Laser Beam of NdFeB has been studied since 2016 as a way to produce complex-shaped dense parts without any binder; most of the works are based on a commercial Nd-lean spherical powder. In the present work, a close-to-industrial process route was developed in order to produce a narrow-distributed 40-μm Nd-Fe-B powder with a composition close to the usual sintered magnet grades. This powder was used to additively manufacture parts and study the impact of changing the laser scanning strategy on the magnetic properties.
