Description

The effects of γ-radiation on the corrosion of Stellite-6, were studied as a function of pH, temperature (25< T< 150 oC), and solution conditions (ionic strength). The type and thickness of the oxide formed and the cobalt content were analyzed. The results show that γ-irradiation increases the cobalt oxidation rate, but this effect varies with pH and temperature. The increased cobalt oxidation rate at pH 6.0 leads mostly to increase of the rate of cobalt dissolution in all range of temperature, whereas the increased oxidation rate at pH 10.6 mostly increases the rate of oxide growth.
