Description
Summary: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 good magnetic properties ( \mu = 748, H_{C}= 87.7 [A/m] ) especially after annealing treatment at 1200° C for 1h ( \mu = 3224, H_{C}= 69.1 [A/m] ), making it a promising material for use in electromagnetic actuators.
