Low cost dry coating system for high efficiency soft magnetic composites

Currently, the materials used for (dielectromagnetics) soft magnetic composites are processed by complex wet processing techniques typically incorporating volatile and flammable organic solvents as a media to form insulating coatings on iron powder. The resultant functionalised powders are substantially value added.

Within this project we have developed an effective low cost alternative route for developing such coatings based on dry blending technology with suitable additives, which can be readily accomplished using standard powder processing equipment routinely available within all powder metallurgy component manufacturers.

This offers an opportunity either for the production and supply of very low cost proprietary coated powders by powder manufacturers, or alternatively for the licensing of the coating technology (and the supply of the appropriate coating chemicals) to component producers to enable them to modify powders in house to their own specifications at low cost.
