Characterization of LPBF Produced Fe2.9wt.%Si for Electromagnetic Actuator

This study aims to produce Fe2.9wt.%Si ferromagnetic material via laser powder bed fusion(L-PBF) for the realization of electromagnetic actuators (EMA). This study is necessary as there are no documents in scientific literature regarding the manufacturing of Iron-Silicon plungers using the L-PBF additive manufacturing (AM) technique. The microstructure, and magnetic properties were characterized using various techniques. The results indicate that the samples produced via L-PBF process exhibit goodmagnetic properties (mu=748,HC=87.7[A/m]) especially after annealing treatment at 1200(degrees)C for 1h(mu=3224,HC=69.1[A/m]), making it a promising material for use in electromagnetic actuators
