Business targets
The R&D team is implementing a project to develop a technology to produce magnetic cores from high-silicon powders using 3D printing.
Compared to traditional electrical steels containing 3% silicon, high-silicon alloys based on iron with a silicon content of more than 6% have a higher magnetic permeability, low remagnetization losses in a wide frequency range and practically zero magnetostriction, which can significantly reduce noise during operation of electrical devices.
However, industrial production of high-silicon alloys is difficult due to their embrittlement during rolling due to formation of brittle phases.
Using 3D printing technologies prevents formation of brittle phases, and opens up the possibility of creating magnetic cores of a fundamentally new topology.
Implementation feuteres
The process of 3D printing with metals consists in sequential layer-by-layer fusion of metal powders using laser radiation.
The structure of printed metal products depends on both the construction technology and the settings of the 3D printer.
When selecting the optimal parameters for 3D printing, several problems must be solved simultaneously: on the one hand, the printed product must have the required mechanical strength, and on the other hand, it is required to form an optimal magnetic domain structure.
Another key factor is the selection of the metal powder. To form uniform layers of powder in the & nbsp; selective fusion process, metal powder is used in the form of finely dispersed spherical granules with an optimized percentage of small and large particles.
