Assessment of Surface Roughness and Surface Wettability of Laser Structuring Commercial Pure Titanium

Author(s): Aseel Mohammed Al-Khafaji*

Abstract

Aim: To evaluate the commercial pure titanium disks that structuring by laser in two design (dot and groove) each one with three different laser scan (5, 15 and 25) and comparing with titanium surface that not subjected to any surface structuring (control) through measuring the wettability test and surface roughness test.

Materials and methods: Structuring on the surface of the commercial pure titanium (CP Ti) disks was performed via using fiber laser CNC machine in two design (dot and groove) in three different laser scans (5, 15 and 25), then the structuring disks analyzed with the control group by atomic force microscope and water contact angle test.

Results: The results of this study showed that the surface roughness and the wettability of commercial pure titanium disks for the dot and groove structuring design increased with the increasing of the laser scans. The result also show that laser structuring with dot design for any laser scan showed higher wettability and roughness values when compared to the groove design for the same laser scans.

Conclusion: The surface roughness and the wettability of the CP Ti disks increased when dot and groove design laser surface structuring were applied to the CP Ti disks especially at 25 laser scans.
