Abstract

Effect of thiourea in acidic sulfate solution on electrochemical corrosion behavior of bulk nanocrystallized ingot iron (BNII) was investigated in 0.1 M H₂SO₄ + 0.25 M Na₂SO₄ solution at room temperature by electrochemical impedance spectra (EIS) and potentiodynamic polarization method (PDP), compared to that of coarse polycrystalline ingot iron (CPII). The results show that For CPII, an inductive loop appears in the Nyquist plots after 5 minutes, immersion. With the increase of immersion time, the Nyquist plot of CPII is not a perfect semicircle; the Nyquist plots of BNII contain two capacitive loops with two time constants. The inhibition of thiourea to BNII is very limited. However, thiourea promoted the dissolution of BNII. The polarization curves for both samples show the presence of a desorption potential. When the potential is higher than the desorption potential, the anodic dissolution current increases very abruptly.

Key words: materials failure and protection bulk nanocrystallized ingot iron(BNII) thiourea(TU) desorption
