Abstract
Additively manufactured metal–insulator layered structures are facing a contradictory demand. Laser sources with different wavelength are required to melt the two materials. In the present study we attempt to additively manufacture metal–insulator composite using a fiber laser. Three different procedures are presented. Firstly, production of a core–shell soft magnetic composite by laser-powder bed fusion technology from a unique amorphous alloy. Lastly the preparation of Fe-Si and Fe-TiN layered structure is discussed. Further improvement of Fe-TiN can be achieved by oxidation heat-treatment. Microstructure, porosity and complex permeability spectra were studied.
