AIR SEAL WITH ABRADABLE LAYER COMPRISING MAXMET COMPOSITE POWDERS AND METHOD OF MANUFACTURING THEREOF

摘要

A method of manufacturing a gas turbine engine air seal (26) comprises forming at least one MAX phase particle (34). The method includes coating the at least one MAX phase particle (34) with a metallic shell (36). The method includes applying the at least one MAX phase metallic coated particle (38) to a surface (20) of a substrate of the air seal (26) to form an abradable layer (32) of a MAXMET composite abradable material from the at least one MAX phase metallic coated particle (38).
