Detailed Processing og Stone Frooring by Laser

Abstract

In the architectural field,polished natural stone is widely favored for floors as well as walls because it imparts a feeling of high quality.However,since the surface of polished stone is very smooth,it becomes slippery,specially when wet.In this study,laser irradiation was used to form small holes on the surface og polished granite stone in order to roughen the surface without significantly affecting the external appearance.It was found that 0.2 to 2mm holes formed on the stone surface by laser were effective in preventing slipping without too much loss of gloss.
