Abstract
A ring segment is arranged to define a gap with a rotating turbine blade. The ring segment includes a substrate and a coating fixedly attached to the substrate. The coating defines a base surface. A ridge is formed as a part of the coating and extends from the base surface away from the substrate to a first surface. The ridge has a first side surface and a second side surface. The first surface extends between the first side surface and the second side surface and partially defining the gap. A first notch is formed on the first side surface at a first location and extends toward the second side surface.

A ring segment arranged to define a gap with a rotating turbine blade, the ring segment comprising:
- a substrate;
- a coating fixedly attached to the substrate, the coating defining a base surface;
- a ridge formed as a part of the coating and extending from the base surface away from the substrate to a first surface, the ridge having a first side surface and a second side surface, the first surface extending between the first side surface and the second side surface and partially defining the gap;
- and
- a first notch formed on the first side surface at a first location and extending toward the second side surface.
A ring segment arranged to define a gap with a rotating turbine blade, the ring segment comprising:
- a substrate;
- a coating fixedly attached to the substrate, the coating defining a base surface;
- a groove formed on the coating, the groove having a first side surface that extends from the base surface to a first surface and a second side surface that extends from the base surface to a second surface, the first surface and the second surface cooperating with the rotating turbine blade to define the gap;
- and
- a first notch formed on the first side surface at a first location and extending away from the second side surface.
