Claims21
An abradable seal for a component comprising:
- a pattern cut into a surface of an abradable seal material with a laser effective to provide improved abradability in the area of the pattern,
- wherein said abradable seal material seals the space between the component and an adjacent surface movable relative thereto by being abraded by relative movement between the component and the adjacent surface and wherein the pattern is cut in an area and to a depth which the adjacent surface will abrade in creating a seal.
A gas turbine engine component comprising:
- a component having an abradable seal applied thereon, the abradable seal having a pattern cut into a surface of an abradable seal material with a laser effective to provide improved abradability in the area of the pattern,
- wherein said abradable seal material seals the space between the component and an adjacent surface movable relative thereto by being abraded by relative movement between the component and the adjacent surface and wherein the pattern is cut in an area and to a depth which the adjacent surface will abrade in creating a seal.
