Abstract
In this paper, a soft magnetic composite (SMC) material, FeSiCr, is analyzed for its beneficial electromagnetic properties and unique 3D formation capacity, which endows a very high potential to become the material for electric motor fabrication by 3D printing technology adopting high temperature selective laser melting (SLM) process. A microscopic and spectroscopic experiment performed on FeSiCr after SLM process showed that FeO is the oxide layer responsible for the unique advantages of this material. Furthermore, FeSiCr is proved to have lower core loss and eddy current loss at high frequency via the comparison analysis between FeSiCr and silicon steel sheet, a popularly used material for electric motor construction.
Highlights
A three-dimensional (3D) additive manufacturing process is capable of forming any complex structured object by stacking a melted addictive material(s) according to the input command of the designer
soft magnetic composite (SMC) used in selective laser melting can be affected by many different factors, such as its alloy composition, microstructure, particle shape and size, density, and oxide layer
To find the optimal structure, the scanning speed was set to 600 mm/s and laser power at 150W for “line sample”. Different oxygen concentrations, such as 1000ppm, 4000ppm and 8000ppm, is added in the chamber to observe the thickness of the oxide layer in the samples, which plays an important role in SMC structure
Summary
A three-dimensional (3D) additive manufacturing process is capable of forming any complex structured object by stacking a melted addictive material(s) according to the input command of the designer. SMC used in selective laser melting can be affected by many different factors, such as its alloy composition, microstructure, particle shape and size, density, and oxide layer. Instead of the traditional heat-pressing process, the selective laser melting provides solutions to improve the high porosity issue thereby enhance the 3D structure and magnetic properties of the SMC material.
