Figure 1.
Representative SEM images of the different polished, sandblasted, femtosecond laser-treated and sandblasted + femtosecond laser-treated titanium disk surfaces used in the preliminary experiments: (A) polished titanium (pTi) at different magnifications; (B) sandblasted titanium (STi) at different magnifications; (C) femtosecond laser-treated titanium (FTi) at different magnifications; (D) femtosecond laser-treated and sandblasted titanium (FSTi) at different magnifications. The second and third columns in each group are low-magnification images of the samples.
