| Popis: | This paper presents a method for microstructuring a metal surface by the radiation of a pulsed fiber laser with a scanner system for displacing the light beam. Specified topographical relief is modeled in a graphic editor, after which it is fabricated on the experimental material. A parameter matrix is created that makes it possible to determine the optimum operating regimes of the laser apparatus for processing the specific material. Three stages of the microstructuring process are described (profiling, cleaning, and polishing), along with the corresponding geometrical parameters of the fabricated structures. A method of reducing the relief roughness Ra and Rz is developed. |
