Beschreibung:
2Y-TZP/Al 2 O 3 hybrid nanoparticles prepared by CO 2 laser covaporization (CoLAVA) were wet mixed with biocompatible lamellar Ta metal particles (20 vol%) and consolidated by spark plasma sintering. The microstructure and mechanical properties of this novel ceramic–metal composite have been studied. The achieved results demonstrate that both the homogeneity of the 2Y-TZP/Al 2 O 3 nanocomposite matrix and the reinforcement with a micrometer-sized ductile phase are prerequisites for the successful design and fabrication of ceramic–metal composites with high strength (1300 MPa), enhanced fracture toughness (16 MPa·m 1/2 ), and improved low-temperature degradation resistance.
