The Environment Influence on Bladed Steel during Operational Conditions

Abstract:

The paper deals with a problem of stress crack initialization on surface of low pressure steam turbine blade during operational regime. The mention stress analysis together with described environment indicate procedure of experimental works. The other goals of research should lead to a concept of assessment methodology of resistance of moving blades against corrosion and technology increasing fatigue strength of blade steels using surface strengthening. A prototype of the moving blade of the low pressure stages of steam turbine with the increased corrosion resistance should be an output of developed efforts.
