Abstract

The surface modification effects on the corrosion resistance and electromagnetic properties of iron-based soft magnetic composites (SMCs) were investigated in this study. Sodium stearate surface modification improved the mixing compatibility between phosphatized iron powder and epoxy resin. Sodium stearate reduces the friction between particles and between the particles and die wall during compaction. Reduced friction thereby increases the compaction density and abrasion resistance. The initial permeability was decreased with increasing sodium stearate concentration. The phosphatized iron powders with sodium stearate surface modification possessed lower imaginary permeability and core power loss than samples without surface modification.
