Synthesis and Characterization of Nitrogen Implanted Titanium Alloys
Nitrogen implanted titanium alloys with enhanced wear resistance have been synthesized under the conditions of energy and N++N2 +ion dose in the range of 30keV to 120keV and 3×1017ions/cm2 to 1×1018ions/cm2, respectively. Auger electron spectroscopy and X-ray diffraction show that supersaturated titanium solid solution with the gradient nitrogen concentration and titanium nitride compounds are formed in the surface modified regions of the materials. Enhanced wear resistance of the nitrogen implanted titanium alloy at energy of 120keV and ion dose of 1×1018ions/cm2 has been showed and explained on the basis of observed microstructure including the formation of micropits on the wear track in the present study.
