Magnetic Materials TRIZ Cases
- Sickle-Shaped Magnet Arrangement for Rotational Angle Detection
A sickle-shaped magnet arrangement generates a pure sine wave through segmented asymmetric geometry and controlled magnetization directions.
- Sintered Magnet Manufacturing via Dimension Correction
Pressure molding corrects NdFeB magnet dimensions before sintering, eliminating grinding waste and reducing thermal stress on equipment.
- Core-Shell R-T-B Sintered Magnet Reducing Heavy Rare Earth Cost
A core-shell microstructure localizes heavy rare earth elements in grain boundary shells to maintain coercivity.
- Corrosion-Resistant NdFeB Magnet with Cobalt Grain Boundary
Cobalt-enriched grain boundaries improve corrosion resistance in sintered neodymium-iron-boron magnets.
- Rare Earth Alloy Flake Production via Strip Casting and Heat Treatment
Strip casting followed by precise heat treatment yields uniform rare earth alloy flakes, resolving low component recovery in magnet pulverization.
