Corrosion of cast Stellite-3 analogue in simulated PWR conditionsTools Karimi, G.N., Shipway, P.H., Stewart, D.A. and Hussain, T. (2018) Corrosion of cast Stellite-3 analogue in simulated PWR conditions. Corrosion Science . ISSN 1879-0496 Full text not available from this repository.AbstractWear resistant alloys are required for deployment of pressurised water reactor primary circuits and in this context, the corrosion behaviour of a cast cobalt-based alloy following exposure for 30 days in lithiated water at 300°C was investigated. Corrosion of the surface was observed, resulting in the formation of a ~100 nm thick chromium and silicon-rich oxide. Preferential corrosion of the matrix at its interface with just one of the carbide types was observed to a depth of ~1 μm; for the first time this was found not due to any inhomogeneity in the matrix but was instead an electrochemical effect.
