【 摘 要 】

This paper presents a method of metal surface microstructuring by means of radiation of an impulse fiber laser with a scanning system, used for the displacement of the light beam. The topographic relief being presented was modeled in the graphics editor and then was manufactured on the experimental material. We also created a «parameter matrix», which allows to determine the optimal modes of operation of the laser system for treatment of a specific material. The paper describes three stages of the microstructuring process: profiling, cleaning, and polishing, and the corresponding geometrical parameters of the structures manufactured. A method for decreasing the level of relief roughness (for Ra and Rz) was developed.
