The enhanced scanning speed led to a decrease in the presence of laser nanoparticles on the surface, impacting both the roughness and period of the LIPSS. This resulted in a lower CA, specifically observed at a laser fluence of 0.16 J/cm2. With an increase in scanning speed from 100 to 500 mm/s, the period of the LIPSS expanded from a range of 220–310 nm to 440 nm.
