Abstract Scope |
Compared to metals, laser additive manufacturing of ceramic materials is more challenging because of the intrinsic brittleness of ceramics and the high temperature gradients, which can induce significant defects and cracking. This presentation shows our novel research on the successful additive manufacturing of yttria–stabilized zirconia (YSZ) ceramics by a laser engineered net shaping (LENS) process. The microstructure formation, such as phase composition, grain size, and crack density, has been carefully characterized by neutron diffraction and electron microscopy, which are correlated with the LENS conditions such as the laser power. Phase transformation from monoclinic to tetragonal/cubic occurred during the LENS of YSZ ceramics. The crack density inside the manufactured parts was reduced at a higher laser power. |
