Abstract: | The Mo surface modified layer on titanium was obtained by the plasma surface alloying technique. The structure and composition
of the Mo modified titanium were investigated by X-ray diffraction (XRD) and glow discharge optical emission spectroscopy
(GDOES). The Mo modified layer contains Mo coating on subsurface and diffusion layers between the subsurface and substrate.
The X- ray diffraction analysis of the Mo modified titanium reveals that the outmost surface of the Mo modified titanium is
composed of pure Mo. The electrochemical corrosion performance of the Mo modified titanium in saliva was investigated and
compared with that of titanium. The chemical corrosion performance of the Mo modified titanium in 37 °C saliva was investigated
and compared with that of titanium. The experimental results indicated that self-corroding electric potentials and corrosion-rate
of the Mo modified titanium were higher than that of titanium in saliva. Corrosion-rate of the Mo modified titanium was lower
than that of titanium in 37 °C saliva. |
