“…All G/Al 2 O 3 composite ceramics obviously displayed relatively high compact structure and less large porous structures comparing to previous DIW 3D‐printing ceramics. [ 15,16,26 ] The different result was attributed to high solid content of inorganic particles and thermal drying of present DIW 3D‐printing ceramics. However, lots of micrometer‐scale pores were clearly observed, resulting from water evaporation of hydrogel and degradation of organic composition.…”

A new graphene (G)/Al2O3 composite ceramic with tunable mechanics is prepared by direct ink writing (DIW) 3D‐printing technology. It is found that the bending strength, fracture toughness, and hardness all increase with increasing in content of G. The bending strength, fracture toughness, and hardness of G/Al2O3 composite ceramic (4.0 wt‰) are improved to be 45.0%, 40.6%, and 21.9% comparing to Al2O3 ceramic, respectively. The result is attributed to good reinforcement of G and inhibition of Al2O3 phase growth by G. Furthermore, the gear wheel with gradient mechanics is also designed and fabricated by the DIW 3D‐printing technology from various G/Al2O3 composite gels. It exhibits excellent wear resistance and low generation of heat during rotational friction. Herein, a new method is provided to fabricate G‐based ceramics with gradient structure and mechanics for various applications.
