Abstract
Titanium (Ti) has poor tribological and mechanical properties such as
low hardness and wear resistance. In this study, we considerably improve
Ti’s hardness by laser ablation method. Ambient air, N2 gas chamber
and N2/liquid water environments were separately selected as irradiation
environments and their effect was comparatively studied on Ti treatment
surfaces. The fabrication of titanium nitride (TiN) structure was successfully
confirmed by XRD analysis in N2 gas and N2/liquid water as irradiation
media. Accordingly, there was good adhesion between TiN structure and
Ti’s surface. Vickers hardness test indicated the laser treatment and TiN
structure significantly improved Ti’s hardness. The formed TiN structure
in N2/liquid water environment had the highest hardness value of 530Hv
comparing to hardness of ablated Ti in N2 gas (370Hv) and air (340Hv).
The escalation of Ti hardness and generation of TiN structure with lasertreatment
in N2/liquid water environment is a favorable aspect of this method.
