中文摘要

This paper presents a novel technique for coloring stainless steel utilizing a fiber laser. This
study develops a processing technology that uses a fiber laser as a laser marking tool, and varies
processing parameters such as pre-surface-processing conditions, stainless steel type, line distance,
laser power, engraving speed, and laser pulse frequencies to achieve different results. This study
investigates the results of the stainless workpiece coloring using optical microscope (OM). This study
shows that polished stainless steel 316 exhibits the best engraving effect. With this material, the line
distance, laser power, engraving speed, and pulse frequency of the laser change the oxidation
thickness. The color of the processed workpiece also changes as the oxidation thickness changes due
to the interference caused by the different thicknesses of the oxidation layers. Results prove that fiber
laser processing of stainless steel is a promising and efficient technique for coloring stainless steel.
