摘要： Disclosed herein is a method of coating, comprising providing an article having an internal passage therein to be coated; electrolytically applying a first layer that comprises chromium or a chromium alloy onto a surface of the internal passage; electrolytically applying a second layer comprising aluminum or an aluminum alloy onto the first layer; and heat treating the article to promote interdiffusion between the first layer and the second layer.

摘要： A method for fabricating a component according to an example of the present disclosure includes the steps of depositing a stoichiometric precursor layer onto a preform, and densifying the preform by depositing a matrix material onto the stoichiometric precursor layer. An alternate method and a component are also disclosed.

摘要： 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.
