Mitigation of stress corrosion cracking of structural materials exposed to a high temperature water

A method for mitigating stress corrosion cracking, comprising:

• reducing corrosion potential via introducing a plurality of catalytic nanoparticles in a high temperature water system;
• and
• inducing, via an effective reduction of corrosion potential, entry of a material comprising zinc into a stress crack in a component in the high temperature water system.

A method for mitigating stress corrosion cracking, comprising:

• catalytically recombining oxidants and reductants to reduce corrosion potential in a high temperature water system;
• and
• inducing, via an effective reduction of corrosion potential, entry of a first material comprising zinc into a stress crack in a component in the high temperature water system.
