Abstract

The effect of ?-radiation on the corrosion of Stellite-6 has been studied by characterizing the oxide films formed at 25°C and 150°C at pH25°C 10.6. The effect of oxygen (aerated solution) on the film formation has also been determined at 150°C. Results show that anodic oxidation is highly promoted by irradiation at 150°C, leading to thicker oxide layers and potentially more cobalt dissolution. Surface analysis results indicate that the film formed on Stellite-6 after irradiation in a basic solution at 150°C mainly consists of CoO/Co(OH)2. Dissolved oxygen (aeration) increases the ratio of CoO to Co(OH)2 in the oxide film and the content of CoCr2O4 and Co3O4 in the film.
