METHOD FOR APPLYING RESISTANT COATING TO FRETTING WEAR AT HIGH TEMPERATURE

摘要

PROBLEM TO BE SOLVED: To provide a method for applying a fretting-wear-resistant coating that is suitable for use in rotor blade components of a compressor or a turbine and can be removed, which can apply the coating again after having inspected and repaired the component, and can return the component to an operating state.;SOLUTION: The rotor blade (30) which can be inspected and repaired is obtained by the steps of: preparing a rotor blade (30) of a gas turbine engine having a mating surface which comes in contact with a corresponding component of the gas turbine engine as a substrate; and applying a high temperature bond coat (22) onto the substrate by using an atmospheric plasma spray technique.;COPYRIGHT: (C)2008,JPO&INPIT
