ABSTRACT: Generally, materials with high biocompatibility are more appropriate for bone and tissue transplant
applications, due to their higher effectiveness in the healing process and infection problems.
This study presents the effects of laser surface texturing on the surface topography properties,
roughness, and wettability of thin titanium sheets, which consequently enhance the biocompatibility
of this material. Creating line patterns across the surfaces, the titanium samples are prepared
using variety of laser parameters. The apatite inducing ability of each sample is tested
through the use of simulated body fluid (SBF). The final biocompatibility level of titanium samples
is analyzed through wettability, surface angle measurements, and average surface temperature
profile. Overall, the effects of laser parameter, pulse numbers, upon the biocompatibility of titanium
are thoroughly examined, with results indicating that a scanning speed of 100 μm/ms results
in desirable bone type apatite inducing abilities across the surface of treated titanium sheets.
