A gas turbine engine article includes a substrate that has a pre-bond surface that includes a serpentine groove. A coating is disposed on the pre-bond surface and mechanically interlocks with the serpentine groove.

A method for stripping a coating off of a blade includes discharging liquid nitrogen through a nozzle onto the blade at a coating to cause lifting of the coating from a substrate of the blade and traversing the nozzle along the blade to cause peeling of the coating off of the substrate of the blade as the nozzle traverses the blade.

A method is provided for removing material from a workpiece using a material removal device and a measurement device. The method includes measuring a first dimension of the workpiece at a location with the measurement device. A jet of water is directed from the material removal device to the location to remove material from the workpiece at the location. A second dimension of the workpiece at the location is measured with the measurement device. The first dimension is compared to the second dimension to determine a measured thickness of the material removed from the workpiece at the location.

A method of measuring a coating deposits a layer of coating on an object. A laser beam is projected on the layer of the coating. A reflection of the project laser beam is received by the laser sensor. From this information, the thickness of the layer of the coating on the object is determined. A value related to the thickness of the layer of the coating may then be compared to a desired value.
