In this study, molybdenum was siliconized by pack method which is realized by diffusion of silicon on the molybdenum substrate at high temperature. Coating treatment was realized at 1100°C for 1-4 h. Coated samples were examined by optical and scanning electron microscopy (SEM), Energy dispersive spectroscopy (SEM-EDS) and x-ray diffraction analysis (XRD). Siliconized layer of the coated molybdenum is compact, smooth and porosity free. X-ray diffraction analysis showed that siliconized molybdenum includes MoSi2 and Mo5Si3 phases. The depth of siliconized layer depending on treatment time is changing between 24.2±1.03 µm and 70.6±1.52 µm. While the hardness of the molybdenum silicide layer is changing between 1262.5 and 1791.4 8 HV0.01, the hardness of the matrix is 260 HV0.01.
