Metallic-ceramic composites are considered as materials with functional properties depending on the production methods. In this work, bi-layered composites Ti6Al4V/Al2O3 were obtained using the spark plasma sintering (SPS) technique. The powders (Sulzer Metco) of titanium alloy Ti–6Al–4V with a spherical shaped particle and aluminum oxide (Metco 101SF) with an irregular shaped particle were used. The specimens were compressed at 20 MPa and sintered in a shielding gas (argon) medium at the temperature of 1200 °C in an SPS HP 5 for 25 min. The obtained composites were subjected to microstructural analysis using light microscope, scanning microscopy Joel JSM 5400 equipped with EDS. Hydrostatic weighing in deionized water according to the PN EN standard was used to evaluate the relative density.The results showed that hot pressing proces (SPS method) could be used to produce dense bi-layered composites with proper interface properties between Ti6Al4V and Al2O3.Keywords: bilayer, SPS methods, composites
