- Annotation: The influence of laser marking parameters on the decorative characteristics of AISI 304 steel surface was investigated. Changes in roughness (Ra, Rz) and local colour (LC) (averaged RGB value) were studied as a function of laser radiation power, scanning speed, and resolution (linear pulse density). Two resolution modes were used: 508 and 1016 dpi, with a fixed laser beam generation frequency of 20 kHz. The obtained data show a pronounced dependence of surface decorative characteristics on processing parameters. Based on experimental results, recommendations are given for laser radiation parameters for forming patterns with desired colour parameters on the steel surface.
