Magnetic Materials TRIZ Cases

MnSe precipitation improves cut machinability in soft magnetic iron without the magnetic degradation seen with MnS or FeS additions.

Targeted cold-sprayed Dy or Tb beads improve rare earth magnet coercivity while cutting material waste and deposition time.

A core-shell bead structure enables 1-5 micron monodisperse particles with high, uniform Fe3O4 loading for magnetic separation and IVD assays.

TiB2 crystals across grains, boundaries, and triple junctions raise coercivity and squareness while reducing heavy rare-earth dependence.

TiB2 crystals across grains and grain boundaries raise coercivity and squareness in sintered rare-earth magnets without heavy rare-earth dependence.

Stable R-rich and R(Fe,Co)2 grain boundary phases help ThMn12 rare earth magnets achieve higher coercive force and better temperature stability.

Rare earth inertization before MIM debinding prevents oxide and carbide formation, enabling complex permanent magnets with high energy product.

A flexible Dy/Tb-coated film enables uniform grain boundary diffusion on curved NdFeB magnets, raising coercivity with lower rare earth use.

Orthogonal gimbal pivots decouple directive magnet tilt from the compass card, reducing oscillation and reading errors during pitching and rolling.

Binder-bound amorphous or nanocrystalline powder helps a dust core keep permeability under high DC bias while reducing iron loss.

Mixing rare-earth powders with different compositions and anisotropic bulking creates a multiphase magnet with stronger coercive force at lower rare-earth cost.

Dy/Tb-boron alloy powder diffuses along grain boundaries to raise coercivity while limiting remanence loss and allowing batch magnet treatment.

Zr-B and Zr-C phases suppress abnormal grain growth in R-T-B magnets, widening sintering range while preserving coercive force and squareness.

A magnetic abrasive slurry with solid lubricant nanoplatelets improves material removal, surface roughness, and brush life on complex 3D surfaces.

A boride phase on preferential crystal growth planes suppresses abnormal grain growth and preserves coercivity and squareness in R-T-B sintered magnets.

Preheating grain-oriented electrical steel above 50°C, then cooling before electron beam irradiation, stabilizes vacuum and iron loss.

Patterned Dy/Tb powder deposition through a holed organic film improves NdFeB magnet coercivity while reducing rare earth waste and coating cost.

Tight substrate contact around artificial microstructures increases electric field penetration and lifts equivalent permittivity beyond conventional limits.

An insulating-matrix nanogranular film raises flux density while preserving resistance to cut eddy current loss in thin-film inductors.

Magnetic dipoles replace contact-based bistable locking to hold mold supports closed with less wear, maintenance, and sticking risk.

Core gaps above or below a planar conductor reshape magnetic fields to counter skin effect and raise high-frequency current capacity.

Carbon lowers molten alloy surface tension to limit inclusion buildup, improving melt-quench yield while maintaining Sm-Fe-N magnetic properties.

ZrB2 crystals and R-Cu-rich grain boundary junctions raise coercivity in R-T-B magnets while reducing heavy rare-earth use and cost.
