© 2021 Institute of Physics Publishing. All rights reserved.In this paper nanosecond direct laser structuring was investigated for the surface modification of Al2O3 ceramic. A theoretical calculation of the roughness index was carried out according to the Cassie-Baxter model for three different patterns formed on the ceramic surface. The relationship between the assumed area of contact of a water drop with the surface of the material and the contact angle of wetting was investigated. This study shows that surface topography is not the only key factor responsible for surface wettability during nanosecond direct laser structuring.
