Effect of plasma treatment on corrosion-electrochemical interaction between titanium and chloride-nitrate melt

The corrosion-electrochemical behavior of titanium in a chloride melt containing 1–30 wt % sodium nitrate at a temperature of 790–900 K in an argon atmosphere is studied. Depending on the sodium nitrate content, either oxide layers of various structures can appear on the titanium surface or titanium...

Description
Summary:The corrosion-electrochemical behavior of titanium in a chloride melt containing 1–30 wt % sodium nitrate at a temperature of 790–900 K in an argon atmosphere is studied. Depending on the sodium nitrate content, either oxide layers of various structures can appear on the titanium surface or titanium dioxide nanopowder can form in the bulk of the melt. Treating VT-1 titanium with hydrogen or helium high-temperature pulsed plasma substantially changes the morphology and protective properties of the oxide films produced on titanium.
