Development and Evaluation of Corrosion Behaviour of Co-Based Alloys for Power Generators

With the increased demand for electric power and the need to reduce green house gas emission, newer power plants (fossil fuel or nuclear based) are being designed with elevated turbine inlet temperature to improve thermodynamic efficiencies and achieve other benefits. The much severe operating conditions (than that in the existing power plants) presents great challenges to material selections. In this proposed research, several classes of Co-based alloys will be modified and subsequently evaluated under supercritical and high temperature steam conditions for their potential use in Canadian Supercritical Water Cooled Reactor (SCWR), as out-of-core component, and in the advanced ultra-supercritical (A-USC) fossil fuel fired power plant where metal surface temperature can reach as high as 815C. Kennametal Stellite is one of the largest Co-based component providers and the application of Co-based alloys in SCWR and A-USC will greatly benefit its business. TO BR CONT’D
