Description
Soft magnetic materials are an integral part of modern technology, especially in areas such as energy, electrical engineering, automotive and renewable energy. Their properties, such as low hysteretic losses, low coercivity, high relative permeability and low magnetostriction, are crucial for the efficient operation of devices such as transformers, electric motors and inductors. However, the efficient production of these materials requires a thorough understanding and optimisation of the technological processes involved in their preparation.
This work focuses on the simulation and optimization of technological processes for the preparation of soft magnetic materials in order to improve their magnetic, mechanical and thermal properties. Advanced simulation tools such as ANSYS Workbench have been used in the research to enable detailed modelling of the influence of key process parameters such as temperature, pressure, processing time and material composition. The simulations were complemented by experimental methods that provided real data to validate the numerical models. In this work the properties and preparation of Fe-based compacted soft magnetic materials are analyzed. Particular attention was paid to the processes of mechanical surface treatment of powder particles, coating and pressing, which have a major influence on the final properties of the materials. It is expected that optimization of these processes can significantly reduce energy losses, increase magnetic efficiency and improve the mechanical stability of the materials.
