Abstract
In one embodiment, a magnet includes a plurality of layers, each layer having a microstructure of sintered particles. The particles in at least one of the layers are characterized as having preferentially aligned magnetic orientations in a first direction.
Claims29
A magnet, comprising:
- a plurality of layers, each layer having a microstructure of sintered particles,
- wherein the particles in at least one of the layers are characterized as having preferentially aligned magnetic orientations in a first direction.
A product, comprising:
- a part having a plurality of layers of sintered magnetic anisotropic particles,
- wherein the part is characterized by physical characteristics of formation by an electrophoretic deposition process.
A method of forming a magnet, the method comprising:
- forming a structure by electrophoretic deposition, the forming comprising:
- adding a plurality of first particles having magnetic anisotropy to an electrophoretic deposition (EPD) chamber;
- and
- applying a voltage differential across electrodes of the EPD chamber to create an electric field in the EPD chamber for causing electrophoretic deposition of the first particles above a first of the electrodes for forming a first layer comprising the first particles;
- and
- after forming the structure, sintering the formed structure to form a magnet.
