Abstract:

Based on the screen printing mechanism, a novel process to fabricate the complex-shaped ceramic skeleton of 3D co-continuous ceramic-metal composite was investigated by joining 99% Al2O3 ceramic in the green state with ceramic slurry. The microstructures of the jointing interface were then characterized by means of SEM, and the effect of sintering temperature on the mechanical properties of the skeleton was also analyzed. The results indicate that the hole-blockage of skeleton can be successfully overcome by the new process, and that the skeleton sintered at 1450 ℃ is of the optimal bending strength and an interlayer thickness of about 250 μm at the joint.

Key words: ceramic-metal composite, network skeleton, joining, connectedness
