The pack-cementation technique was used to manufacture iron (Fe) silicides on Mirrax steel in this study. In an open atmospheric furnace, pack siliconizing process was performed using silicon (Si), ammonium chloride (NH4Cl), and alumina (Al2O3) at 900-950-1000°C and with variable deposition periods of 2-4-6 h. Utilizing scanning electron microscopy-energy dispersive X-ray spectroscopy, the appearance and structure of silicide layers were examined. It was noted that the silicide layers, which were smooth, uniform, and lacked notable porosity, had good bonding with the matrix. By using X-ray diffraction analysis, dominant phase is Fe3Si was determined. The coating layer thickness increased with process time and temperature. Additionally, the activation energy for the development of the siliconizing layer is determined. Due to the creation of a layer with a smoother morphology, less porosities and oxygen impurities, and an appropriate thickness silicon layer have been obtained.
