Özet
Owing to the advantages of using nanosecond laser pulses to create a specific surface texture on biomedical alloys, laser texturing is considered to be a viable processing approach. In this study, roughness and wettability of surfaces were used to determine how different factors, including frequency (F), scan direction (SD), fill spacing (FS), and scan speed (SS), affect the surface texture of the Ti-6Al-7Nb alloy. It was revealed that the FS significantly (p < 0.05) influenced the surface roughness parameter (Sa) and contact angle (CA); an increase in the FS value resulted in smoother surfaces exhibiting higher mean CA. The SS significantly (p < 0.05) affected the mean Sa; the SS of 800 mm/s showed the lowest mean Sa. Lower mean Sa values and higher mean CAs were obtained as FS, SS, and F were increased. The texture of surface topography is highly affected by both pulse-to-pulse and hatch overlap ratios. The parameter with the slightest effect on CA and Sa, according to process optimizations, was found to be F. The surfaces exhibited superhydrophilic and hydrophilic properties. The textured surface with the highest CA of 75

exhibited a Sa of 1.58 μm. The surface with the highest Sa value of 10.25 μm exhibited superhydrophilic properties. The surface textured with the process parameters of 0

SD, 800 mm/s SS, 100 kHz F, and 0.01 mm FS exhibited the smoothest surface with a Sa value of 1.21 μm.
