Abstract:

A method for repairing a flow path surface of a case for a variable vane assembly includes measuring a wear depth at a location within a wear recess formed in the flow path surface of the case, determining a coating thickness corresponding to the wear depth at the location, and repairing the flow path surface of the case by applying a coating to the wear recess, where the coating has the coating thickness at the location.

Abstract:

A method for repairing a pocket of a case for a variable stator assembly may comprise: receiving, via a processor, a plurality of wear depths, each wear depth in the plurality of wear depths corresponding to a wear portion in a stator pocket in a plurality of stator pockets; determining, via the processor, a plurality of thicknesses of a coating to be deposited based on the plurality of wear depths, each thickness of the coating in the plurality of thicknesses corresponding to the wear portion for each stator pocket in the plurality of stator pockets; and commanding, via the processor, a coating spray torch to deposit the coating in the wear portion of each stator pocket in the plurality of stator pockets.
