  • Thermoplastic coated magnetic powder compositions and methods of making same
    Patent number: 5306524
    Abstract: An iron powder composition comprising an iron powder coated with a substantially uniform coating of a thermoplastic material and admixed with a boron nitride powder and a method of utilizing the mixture to produce a magnetic core component is provided. The iron powder mixture is formulated with up to about 1% by weight of boron nitride which reduces the stripping and sliding die ejection pressures during high temperature molding and also improves the permeability of the magnetic part over an extended frequency range.
    Type: Grant
    Filed: September 15, 1992
    Date of Patent: April 26, 1994
    Assignee: Hoeganaes Corporation
    Inventors: Howard G. Rutz, Christopher Oliver, Brooks Quin
  • Thermoplastic coated iron powder components and methods of making same
    Patent number: 5268140
    Abstract: A method is provided for producing a high strength iron based component by powder metallurgical techniques but without sintering. A powder composition of iron-based particles coated or admixed with a thermoplastic material is compacted under heat and pressure by traditional powder metallurgical techniques. The pressed component is then heat treated at a temperature above the glass transition temperature of the thermoplastic material for a time sufficient to bring the component to the heat treatment process temperature. The resulting component has increased strength and can be used as a structural component or as a magnetic core component.
