Surface Modification of Pure Titanium Implant Using Acid and Alkali Treatments

27747

In the present study, commercial pure titanium (Cp-Ti) samples were subjected to various acid and alkali solutions to study the role of surface roughness, which is important in terms of biocompatibility, on liquid contact angle of implant surfaces. For this purpose, the surfaces of titanium samples were etched by mixtures of acid and alkali for long duration. The surfaces of treated samples were characterized using mechanical profilometer, optical tensiometer for measurement liquid contact angle and scanning electron microscopy. In the results, it was observed that the contact angle of titanium implant increased with the increase in the surface roughness values on titanium surfaces. The surface roughness and liquid contact angle values of the samples with 1K, 2K and 3K codes decreased, whereas they increased for the samples with 4K, 5K and 6K codes when compared to the original titanium. This case indicated that the first three chemical treatments created hydrophilic property on titanium surfaces.
