abstract This article presents the results of studies concerning the production technology and properties of 316L-HAp composite materials sintered at temperatures of 1000 and 1100°C with compaction pressures of 5, 25, and 50 MPa. The spark plasma sintering method (SPS) was applied for the purpose of producing these materials. 316L-HAp composites characterized by densities ranging from 5.45 to 6.01 g/cm3 were the final products of the applied process. The results of absolute porosity measurements are discussed. It is shown that as sintering temperature and compaction pressure increase, so does the sinter's apparent density and compression strength, although an Rc value that is lower by 8% is observed for sinters produced at a temperature of 1100°C compared to those produced at a temperature of 1000°C. Hardness decreases as sintering temperature increases and reaches the highest values in sinters produced with a compaction pressure equal to 25 MPa.
