METHOD FOR FORMING SURFACE STRUCTURE OF ZIRCONIA-BASED CERAMIC, AND ZIRCONIA-BASED CERAMIC
Provided herein is a method for forming a periodic microstructure on a surface of zirconia-based ceramics, which are not easily mechanically workable, without causing thermal adverse effects. A zirconia-based ceramic having a surface periodic microstructure is also provided. A linearly or circularly polarized laser beam is irradiated to a zirconia-based ceramic surface, and periodic irregularities are formed in a spot of the laser beam. Stripe-pattern irregularities parallel to the direction of polarization can be formed in a spot of a laser beam by irradiating a linearly polarized ultrashort pulsed-laser beam to a zirconia-based ceramic surface. A mesh-like raised region and a dot-like recessed region can be periodically formed by irradiating a circularly polarized ultrashort pulsed-laser beam to a ceramic surface.
