Laser surface texturing provides several benefits such as improved tribological behavior of the surface, reduced friction, increased anti-adhesive properties and improved wettability and lubrication applications. Even though, surface topography or surface roughness resulting from laser processing of steel surfaces have been studied in literature, the relation between laser texturing parameters and scale-limited areal surface texture parameters are not as much investigated and correlated. Fiber lasers provide a flexible solution for texturing different materials with different surface structures. In this paper, laser surface processing and texturing of tool steels is considered, and a nanosecond fiber laser system is utilized to scan and texture the surfaces of AISI D2 tool steel under a shield of Argon gas to prevent oxidation. The effects of laser energy density, scan velocity, and strategy on the texture line width and resultant areal surface texture parameters have been investigated. It was found that Argon gas during laser texturing of tool steel helps to achieve not only less heat affected zone but also slightly lower surface roughness indicating that the application of an inert gas requires further investigations.
