Abstract

A (FeCrCoNi)_100−xTi_x system was designed and prepared, and the corrosion behavior of the alloy in NaCl and H₂SO₄ was studied. Potentiodynamic polarization curves and EIS tests show that the passive corrosion current density decreases with the increase of Ti content. XPS analysis shows that the passive film has a double-layer structure, and the outer TiO₂ of the passive film and the Cr₂O₃ of the inner layer play an important role in the corrosion resistance of the alloy. With increasing Ti content, the density of carriers in the passivation film decreases, and the alloy passivation film is denser and has better protection performance.
