Abstract

C.P. Titanium and Ti-13Nb-13Zr alloys are widely used in biomedical applications as dental and orthopedic implants. However these materials are vulnerable to Surface corrosion. The aim of this investigation is to enhance the corrosion resistance of the above alloys through laser nitriding technique. Laser nitriding was performed using Nd: YAG laser. The Electrochemical properties of nitrided layer will be investigated in simulated body solution using potentiodynamic polarization technique. The results will be compared with those obtained on untreated alloys tested in same conditions. The laser nitrided and the corroded samples will also be characterized using XRD and SEM. The enhancement of wear resistance of the above samples will also be presented in this paper.
