AbstractThe corrosion resistance of Al-based amorphous alloy can be significantly improved with the addition of NaNO3 into NaCl solution. The growth rates of passive film in the initial stage of immersion are accelerated, and the metastable pitting is inhibited. The pitting potential of Al-based amorphous alloy is increased with the concentration of NaNO3, and the pitting corrosion is completely avoided when the concentration of NaNO3 is above 0.03 M. The transition from pitting to transpassivation can be attributed to the incorporation of NO3- in passive film. Sodium nitrate is an efficient corrosion inhibitor for Al-based amorphous alloy.
