| Abstract Scope |
Hydrogen is known for having adverse effects on the mechanical properties and creep behaviour of many metals. Hydrogen insertion during corrosion has been shown to occur during the oxidation of aluminum, and the sulfidation of steels under certain conditions. The calibration of hydrogen content to the lattice parameter of copper is an important standard to establish for the comparison of as-received and corroded copper samples. The proper characterization of copper materials is important to build confidence on the long-term performance of copper coatings as it pertains to Canada’s plan for the storage of used nuclear fuel in a deep geological repository. Accurate measurement of lattice expansion due to hydrogen uptake can serve as a non-destructive characterization method for evaluating hydrogen ingress. The findings of this study do not indicate significant lattice expansion caused by hydrogen ingress in repository relevant corrosion conditions. |
