Abstract:
In some examples, a system includes a blade including a blade tip and a blade track or blade shroud segment including a substrate and an abradable coating layer on the substrate. The substrate defines a leading edge and a trailing edge. The abradable coating layer includes a first tapered portion that substantially continuously tapers from a center portion of the substrate toward the leading edge of the substrate, a second tapered portion that substantially continuously tapers from the center portion of the substrate toward the trailing edge of the substrate, and a blade rub portion that extends between the first tapered portion and the second tapered portion. The abradable coating extends from the leading edge to the trailing edge, and the blade tip is configured to contact at least a portion of the blade rub portion upon rotation of the blade.
