Abstract <p>A study of the AlSi10Mg composite material with the addition of 5, 10, and 15 wt % zirconium nitride powder synthesized by selective laser melting was conducted. A synthesis technique was developed, including the preparation of ZrN powder, its mixing with the matrix alloy powder in a planetary ball mill, and the printing of volumetric samples. Optimum synthesis process parameters were determined, ensuring a high relative density of up to 99.9% of resulting composite. It was found that, at zirconium nitride concentrations in the matrix alloy equal to 10 and 15 wt %, a portion of it reacts with the matrix alloy during melting and forms small particles with the stoichiometry of Zr(Al, Si)₃ phase. A uniform distribution of zirconium nitride particles, both initial and those reacted with the AlSi10Mg alloy, is observed in the microstructure of synthesized samples.</p>
