摘要
The corrosion current density and corrosion potentials of titanium-nickel alloys are determined as a function of a ratio between the alloy components in 0.5 M NaCl solution. For the alloy range from the alloy containing approximately 5 wt % nickel to TiNi intermetallic compound, the corrosion current of the alloys is determined predominantly by titanium, which exhibits a low corrosion rate (below 1 mu A/cm(2)). A certain decrease in the corrosion current as compared with the corrosion current of titanium is observed with increasing content of nickel in the alloy. This is explained by an increase in the polarization of cathodic reaction. At a higher content of nickel, the corrosion behavior of the alloys is determined by this component; the corrosion current increases with increasing nickel content in the alloy.
