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.

Summary
The fields of biomedical and tissue engineering have been expanded immensely in previous decades. (2015) Effects of Laser Pulse Numbers on Surface Biocompatibility of Titanium for Implant Fabrication. An effective way of enhancing the biocompatibility of a material is to alter its surface properties, such as surface structure and topography [3]. The purpose of this paper is to investigate the effects of laser surface texturing on enhancing the biocompatibility of titanium. The surface topography properties of the titanium samples are altered through a range of laser process parameters, and effects of pulse rate on surface structure, roughness, and wettability of titanium are examined. Due to the fact that these parameters vary in a wide range, understanding their effects on surface treatment and biocompatibility could provide an efficient manner for utilizing the lasers for biomedical applications
