Radiation Induced Corrosion Of Stellite-6, Mehran Behazin
Radiation Induced Corrosion Of Stellite-6, Mehran Behazin
Electronic Thesis and Dissertation Repository
This thesis presents a study on the aqueous corrosion of a cobalt-based alloy, Stellite-6. Since aqueous corrosion kinetics are strongly influenced by water chemistry conditions (pH, temperature, and redox agents), a systematic study of Stellite-6 corrosion was carried out. The aim was to develop an ability to predict corrosion behaviour and particularly metal dissolution rates for cobalt alloys under a range of conditions. The work focused on a study of the influence of ionizing radiation on corrosion. This is of particular interest in the nuclear industry where radiation fields are present. Ionizing radiation creates oxidizing radiolysis products and alters the …

A Study Of Gamma Radiation Induced Carbon Steel Corrosion, Kevin Daub
Electronic Thesis and Dissertation Repository
This thesis presents work on the development of a mechanistic understanding of the effect of ionizing radiation on the aqueous corrosion kinetics of carbon steel. Exposed to ionizing radiation, water decomposes into a range of oxidizing (O2, •OH, HO2•, H2O2) to reducing (•eaq–, •O2–, •H) species. The production of the redox active species by radiolysis can have a significant effect on the corrosion behaviour of a metal. Of particular interest is the effect of radiolysis on corrosion when the solution environment, such as temperature, pH, and …

Investigating Interfacial Reactions Of Silver-Containing Films Using Novel Methods, Sarah Danielle Pretty
Electronic Thesis and Dissertation Repository
This thesis presents work on the mechanism and kinetics of the surface film reactions involving the conversion of aqueous species on solid surfaces, and specifically, the reactions of iodide and bromide on silver oxide on silver substrate. These reactions provide a method of immobilizing unwanted halides and are particularly suited to control of hazardous radioactive iodine. Potential applications of this research include nuclear reactor safety and post-accident radioiodine management, and the safe production and use of the medical isotope 131I.
