Nitriding of titanium by NH{sub 3} RF plasma: a study of the corrosion resistance and the mechanical properties of the protective films formed at the solid surface
The exposure of a titanium sample to an NH{sub 3} low pressure plasma leads to the formation of a nitriding layer. The products formed at the titanium surface were identified by XRD spectroscopy. The modification of the corrosion resistance characteristics of titanium due to the NH{sub 3} plasma treatment were investigated by electrochemical tests. The recorded polarization curves of the treated titanium samples were used to determine the values of the corrosion potential E{sub corr}. This study confirms the increasing of the corrosion resistance as a function of the time exposure and the injected electric power in the silica reactor. The plasma treatment also induces drastic changes of the titanium target in hardness.
