In this study, Boronation of Ni-Mg alloy containing 95% Ni and 5% Mg was carried out. In order to produce the alloy material, Ni and Mg metal powders were mixed in a single-phase powder mixer for 24 hours to mix homogeneously in suitable containers by powder metallurgy method. Mixed powders were poured into specially designed cylindrical molds and pressed under 300 bar pressure and then sintered at 530 ° C in tube furnace under Ar atmosphere. The samples produced by sintering were subjected to hardness and density tests respectively. In addition, sintered samples were made by using commercial Ekabor powder at a temperature of 900 and 1000 ° C for 1.5-4.5 hours. The boride layer thickness of the boronized samples was measured by means of an optical microscope. Boron phases were determined by XRD analysis. Boronized Nickel-Magnesium samples yielded Ni3B, Ni2B, NiB and Mg phases as a result of XRD analysis. The boride layers with different thicknesses were measured on the Ni-Mg samples obtained depending on the increasing boring temperature and time. It has caused a porous structure in microstructure in addition to the fact that Mg content helps to boron and affects the growth of boride layers.
