Abstract

An in situ hydrothermal deposition process is being developed to apply a film of zirconia (ZrO₂) onto interior surface of 304 stainless steel and Alloy 600 as a potential method for mitigating intergranular stress corrosion cracking (IGSCC) in boiling water reactors (BWRs). The coating process is discussed. The obtained zirconia coatings are adherent. Monoclinic ZrO₂ is the dominant phase when ZrO(ClO₄)₂ was the oxidant; tetragonal ZrO₂ became the dominant phase when ZrO(NO₃)₂ was the oxidant. A preliminary experiment did not measure significantly lower values of the electrochemical potential (ECP), relative to the uncoated specimen over a wide range of dissolved oxygen in 265 °C water.
