Preparation of Nd-Fe-B Magnets by Screen Printing
Magnetic NdFeB thick films were prepared by screen printing a NdFeB-based ink. The films are isotropic and the thickness varied from 30 microns to 1 mm. The printing parameters were optimized with respect to the mechanical and the magnetic properties of the films. After curing at 390 K good adhesive non porous films were obtained. The magnetization of films are 400 emu/cc, the coercive field Hc is 1 Tesla, the Br is 4 kG and the energy product is 2.7 MGOe (21.5 kJ/m3). Rotors with those magnetic properties tested in stepper motors with promising efficiency.
