METHOD OF FORMING AIR SEAL

摘要

PROBLEM TO BE SOLVED: To provide an air seal for a gas turbine engine having performance excellent more than a conventional air seal by using a conventional device. SOLUTION: This method of forming the air seal for the gas turbine engine includes the performance of plasma spraying of an abradable seal layer 38 on a base material 30 by preparing the seal base material 30, and this plasma spraying includes the performance of spraying of a bulk material of a thermosetting polymer and a thermoplastic binder material. The method of forming the air seal in another form includes adhering of this molded seal material to the seal base material 30 by removing the molded seal material by molding the abradable layer 38 including the thermosetting polymer and the thermoplastic material by preparing the seal base material 30.
