Abstract
A method of manufacturing a gas turbine engine air seal comprising forming at least one MAX phase particle. The method includes coating the at least one MAX phase particle with a metallic shell. The method includes applying the at least one MAX phase metallic coated particle to a surface of a substrate of the air seal to form an abradable layer of a MAXMET composite abradable material from the at least on MAX phase metallic coated particle.
Claims11
An air seal in a gas turbine engine comprising:
- an abradable layer comprising a MAXMET composite material having MAX phase particles coated with a metallic shell.
A gas turbine engine comprising:
- a first structure;
- a second structure rotatable relative to the first structure, wherein one of the first structure and second structure comprises a substrate;
- and
- an abradable layer coupled to said substrate wherein said abradable layer comprises a MAXMET composite material having MAX phase particles coated with a metallic shell.
