Assessment of the Role of Alloying Elements on the Corrosion Behaviour of Ni-Cr-Mo Alloys

The primary goal of this research was to elucidate the key influences of the alloying elements in Ni-Cr-Mo alloys on their electrochemical behaviour. Two alloys, varying in Cr and Mo content, were studied in deaerated 5 M NaCl solutions. As indicated in Figure 1, potentiostatic polarization followed by electrochemical impedance...

Crevice Corrosion of Grade-2 Titanium

Titanium alloys are highly corrosion resistant under oxidizing conditions, but can suffer crevice corrosion at elevated temperatures (>70°C) if the surface is occluded by another material, such as a deposit, a poor weld or a crack. The conditions which develop within a crevice are such that, in the event of...

Electrochemical Study of Doped Uranium Oxide (UO2) in Slightly Alkaline Sodium Carbonate/Bicarbonate Solutions

This recent research project was designed to investigate the influence of carbonate/bicarbonate, the key groundwater constituents likely to influence fuel dissolution inside a failed nuclear waste disposal container, on the reactivity of different uranium oxide (UO2) specimens. A cyclic voltammetric (CV) study of doped UO2 (Dy-UO2, Gd-UO2, 1.5 at% SIMFUEL...

Electrochemical and Surface Analytical Measurements on Cu-Coated Steel Specimens

The proposed Canadian container for the disposal of spent nuclear fuel consists of a dual wall comprised of an outer shell of copper over an inner low alloy steel vessel. Because of manufacturing and fabrication challenges for thick-walled containers, a thin-walled alternative design is being developed. Their fabrication involves coating...

Nanoindenter Installed at SSW

SSW has acquired a Hysitron TI-950 TriboIndenter from the Department of Chemistry, Western University. With the assistance of Professor Emeritus Peter Norton, who was the PI on the NSERC grant application for the initial acquisition of the nanoindenter, we have updated the system with a new stage controller. The instrument...
