A rotary turbomachine includes a rotor mounting at least one disk having an outer surface and at least one bucket (45) extending radially from said outer surface. A stationary stator component (44) is located adjacent the disk, and a seal plate (42) extends from a portion of the stationary stator component (44). An angel wing seal (48) extends from the bucket (45), thereby defining a clearance gap between the seal plate (42) and the angel wing seal (48). An abradable seal element (40) is disposed on the seal plate (42), and the abradable seal element (40) and the seal plate (42) are canted at an acute angle relative to a center axis of the rotor extending radially outwardly in a direction toward the angel wing seal (42). A corresponding method of reducing a seal gap is also provided. |
