Laser engineered net shaping system and pure ceramic powders without any binders was applied to fabricate Al2O3/ZrO2 eutectic thin-wall structures. Optimized processing scope was achieved by systematical experiments. Chemical composition, microstructure, hardness and fracture toughness of the fabricated specimens were then analyzed by XRD, SEM and Vickers, respectively. The results show that, the number of cracks decreases first and then increases with the increment of laser power. When laser power increases to 454 W, the cracks are suppressed apparently, and when laser power becomes higher than 582 W, the cracks begin to increase significantly. The fabricated specimen presents dense eutectic microstructure with about 100 nm eutectic spacing which is comprised of α-Al2O3 and t-ZrO2. Microhardness of the fabricated structure is high to 17.5 GPa and fracture toughness is 4.8±0.3 MPa·m1/2, which are comparable to similar material prepared by traditional methods. This study indicates that the laser engineered net shaping of ceramics based on melting-solidification process provides a new method for rapid fabrication of high-performance ceramic structures.
