Conference paper


Fe/Fe3O4 soft magnetic composite was prepared with the method of physical coating method by spark plasma sintering. In this way, its sintering interface was improved. It solved the problem that hot pressing curing soft magnetic composites have low densification. The Fe/Fe3O4 was observed at different sintering temperatures and the influence of the chemical composition and microstructure properties was analyzed. The material density was higher and interface was combined with high performance. The resistivity decreases because the element changed with higher temperature. The morphology and structure are characterized by SEM, EDS and XRD, respectively and the electric properties are tested. In the end part we discuss the pros and cons of SPS method on synthesizing Fe/Fe3O4 soft magnetic composites and its potential application in industries.
