Abstract

In this study, it was aimed to investigate the electromagnetic interference shielding (EMI-SE) as well as some physical and mechanical properties of pack borided Mirrax tool steel. Boriding process was carried out at 900, 950 and 1000°C for 2, 5,8h, respectively. Optical images showed that borides layer have smooth morphology and flat interface with matrix. XRD analysis revealed that main phases in the layer were FeB and Fe2B. Intensity of FeB phases increased with increment of process temperature and time. Depending on process time and temperature the thickness of borides layer was ranged from 10 mm to 87.80 um. Microhardness of layer was between 1700 and 2400 HV. EMI-SE measurements conducted within Ku band (12-20 GHz) indicated that EMI-SE efficiency increased by increasing of process time and temperature and it was ranged from 52dB to 75dB. It is possible to claim that borided Mirrax steel performed good EMI-SE and when boriding time reached to 5h, remarkable EMI-SE (electromagnetic interference shielding) (over 60dB) was observed on the sample borided even at 900°C.
