COATING FIXTURES FOR GAS TURBINE ENGINE COMPRESSOR DISKS

摘要

A method for coating a gas turbine engine compressor rotor having a compressor disk with axial slots includes inserting masking fixtures into the axial slots. Each masking fixture includes a masking root that matches the shape of a blade root of an axial blade configured to be inserted into the axial slot the masking fixture is inserted into. The method also includes applying a coating to the compressor rotor after inserting the masking fixtures into the axial slots followed by drying the coating on the compressor rotor at a predetermined temperature. The method further includes removing the masking fixtures from the axial slots after drying the coating on the compressor rotor followed by curing the coating on the compressor rotor.
