Biomimetic surface roughness and UV irradiation time will greatly affect their use of hydrophilic and hydrophobic surface of biological material, and then in turn affect cell adhesion, cell growth quality. Therefore, the main purpose of this study in different surface modification treatments on Ti6Al4V discs which around irradiation with UV light influence the wettability on the material surface. Then, Factorial design of experiments is used to understand the relationship between the pattern of Ti6Al4V. The results showed that the wettability on Ti6Al4V is negative correlation with surface roughness and UV irradiation time. There is the contact angle of the smallest and interaction situation on a smoother roughness surface (SG) and modified 60 min irradiation.


Key words: Ti6Al4V, wettability, ultraviolet, surface modification.
