【 摘 要 】

Wettability plays a notable role in success of any bio-implant. It influences tissue amalgamation, protein adsorption and cell attachment at the surface of an implant. Hence, wettability enhancement of the implant is a field of today's dynamic research. In this work, laser based direct melting approach was employed to generate four separate surface patterns on Ti-6Al-4V by means of nanosecond pulse fibre laser. The modification of surface morphology was assessed by means of SEM. Wettability was measured by the help of goniometer. The obtained results revealed that pulsed laser irradiation can substantially improve the biocompatibility of Ti-6AL-4V by making its surface super hydrophilic.
