Abstract:

Objective To change the composition of titanium surface, and improve the wear resistance. Methods Nitrogen was implanted into the surface of pure titanium using plasma ion implantation, the ion implantation dose was 3×1017 ions·cm－2 and 9×1017 ions·cm－2. The change of surface elements was analyzed by energy-dispersive spectrometry. The hardness of the treated samples was evaluated with micro-hardness tester. The wear resistance was measured by nano-scratch tester. The scratch morphology was analyzed by scanning electron microscope. Results The samples modified by plasma ion implantation showed light golden. The ion implantation dose of 3×1017 ions·cm－2 and 9×1017 ions·cm－2 nitrogen atom content of the samples were 24.08% and 35.83%. The hardness of samples after ion implantation was significantly greater than the samples before ion implantation. The friction coefficient of samples after ion implantation decreased significantly. Conclusion After nitrogen ion implantation, hardness increased significantly, wear resistance of pure titanium can also been improved.

Key words: pure titanium, plasma ion implantation, nano-scratch, micro-friction, wear mechanism
