Outline of Final Research Achievements |
Functional surface creation technologies have garnered increasing attention over the years. These technologies can provide various functions to an Implant by establishing a fine structure on the material surface. Our study combined a micrometer-scale V-shaped groove structure using an ultra-precision cutting and nanometer-scale ultra-fine periodic structure (LIPSS) using a short-pulsed laser. Then, we clarified the creation principle and studied the functionality of the structure. As a result, it was found that optical behavior inside the V-shaped groove changed; therefore, the composite structure changed depending on the groove angle, laser polarization direction, and number of times of irradiation.
