This study investigates the integration of zirconia (ZrO2) as a reinforcing agent in the Inconel 718 matrix to potentially enhance material hardness and high-temperature oxidation resistance. Employing laser powder bed fusion (LPBF), 3D composite parts of Inconel 718-ZrO2 were systematically fabricated, varying the zirconia mass. The primary objectives encompass exploring the impact of zirconia on the microstructure, micro-hardness, and high-temperature oxidation of the Inconel 718- ZrO2 composite. The research employed comprehensive testing methodologies, including SEM-EDS, micro-vickers hardness, XRD, and TGA-DTA. Results elucidated the successful 3D printing of Inconel 718-ZrO2 composites utilizing the LPBF. Notably, the presence of defects such as porosity, cracks, lack of fusion, and balling was identified, intensifying with increased zirconia content. The composite demonstrated a substantial increase in hardness across all zirconia mass variations compared to pure Inconel 718, with 1 wt.% zirconia achieving the highest hardness. Furthermore, oxidation resistance exhibited improvement with higher zirconia content in the composite. The comprehensive analysis unveils promising opportunities for the development and application of Inconel 718-ZrO2 composites in industries characterized by hightemperature environments and elevated wear conditions. The findings provide valuable insights into optimizing the performance of these composites, thereby contributing to advancements in materials engineering for challenging operational conditions.
