Abstract

Abstract for CNS Fuel Conference August 2016 Kingston, Ontario Martyn R Wash CNS Member Fretting Corrosion of Zirconium Alloys The term ‘fretting’ is from the field of tribology which describes the localized damage at the adjoining interfaces between two or more materials in relative motion to one another. In most instances, the environmental and mechanical interaction is synergistic whereby the damage at the contact faces is much higher than the individual mechanical and corrosive effects acting alone. It is being suggested that the fretting corrosion rate could be as high as the accumulated oxidation rate corresponding to the exposure time interval for the particular vibration frequency of the fretting agent. An example of a fretting agent is a loose piece of swarf debris. A number of post in-reactor examples of debris induced fretting corrosion are presented. The final paper submission is expected to be 8-9 pages in length.
