Abstract
The present invention is directed to electrically conductive compacted metal parts fabricated using powder metallurgy methods. The iron-based powders of the invention are coated with magnetic or pre-magnetic materials.
Claims26
A method of making a magnetic-coated metallurgical powder composition comprising
- providing a solution comprising a magnetic material;
- stirring an iron-based metallurical powder with the solution so as to uniformly coat the particles of the iron-based powder with the solution to form a coated iron-based metallurgical powder;
- removing the coated, iron-based metallurical powder from the solution;
- removing residual solvent from the coated iron-based metallurical powder.

A method of making a pre-ferrite-coated metallurgical powder composition comprising
- providing a solution comprising a pre-ferrite material;
- stirring an iron-based metallurical powder with the solution so as to uniformly coat the particles of the iron-based powder with the solution to form a coated iron-based metallurgical powder;
- removing the coated, iron-based metallurical powder from the solution;
- removing residual solvent from the coated iron-based metallurical powder.
