Abstract: A wear monitoring system for measuring incursion depth into an abradable coating includes a layer of abradable coating including a depth. At least one measurement circuit includes a plurality of conductive leads disposed within the abradable coating. The conductive leads are spaced radially apart within a common radial plane corresponding to the depth of the abradable coating. A plurality of resistor elements corresponds with the plurality of conductive leads. Each of the plurality of resistor elements are in electrical communication with one of the plurality of conductive leads disposed within the common radial plane of the corresponding one of the plurality of conductive leads. An electrical characteristic of the circuit varies responsive to cutting of one or more of the plurality of conductive leads by a passing airfoil. A gas turbine engine and method are also disclosed.

Abstract: A gas turbine engine includes an airfoil having a core that has a first hardness and a surface on the core. The surface includes a plurality of geometric features that have a second, greater hardness. The geometric features define a surface porosity by area percent and a corresponding surface solidity by area percent. The surface includes a ratio of the surface solidity divided by the surface porosity that is 1.8 or greater. The geometric features and the ratio establish the surface to be hydrophobic, and the second, greater hardness and the ratio establish an erosion rate of the surface that is equal to or less than an erosion rate of the core under identical erosion conditions.
