Abstract
Electrochemical polarization analyses were conducted to investigate the impact of different oxide structures on corrosion resistance of ZrO2-treated Type 304 stainless steel specimens in high temperature water. All specimens were pre-oxidized in high temperature water containing either 300 ppb dissolved oxygen or 50 ppb dissolved hydrogen, followed by a hydrothermal deposition treatment with ZrO2 nanoparticles. Experimental results revealed that the corrosion potentials and corrosion current densities on the ZrO2-treated specimens were lower than those on the untreated ones, and the decreases in these parameters were more distinct on the ZrO2-treated specimens with oxides developed under dissolved oxygen condition.
