摘要： Disclosed herein is a rotor assembly for a steam turbine including a stacked rotor section having rotor plates. The rotor plates include a main body portion having a plate shape and a first axial face and a second axial face opposite to the first axial face. The rotor plates also include an airfoil base surface at an outer radial edge of the main body portion. The rotor plates further include buckets which extend radially outward from the airfoil base surface. And the rotor plates yet further include a seal disposed to prevent steam exposure to the first and second axial faces.
