Abstract
A method of remanufacturing a seal surface includes forming a groove into a component surface at a location of a worn seal surface. A bead of new seal material may then be deposited in the groove by laser cladding. The bead of new seal material may then be machined to form a new seal surface that is generally flush with the component surface.
Claims19
A method of remanufacturing a seal surface comprising:
- forming a groove in an interfacing surface of a component at a location of a worn seal surface;
- depositing seal material within the groove by laser cladding;
- and
- machining the seal material to form a remanufactured seal surface that is generally flush with the interfacing surface.

A method of remanufacturing a seal surface comprising:
- forming a groove in an interfacing surface of a component made of a first material, the groove having a ratio of width W to depth D of at least 4.0:1;
- depositing a second material in the groove by laser cladding, the second material being different than the first material and being metallurgically bonded to the first material;
- and
- machining the second material to form a remanufactured seal surface that is substantially flush with the interfacing surface of the component.

A method of remanufacturing a seal surface comprising:
- forming a groove in an interfacing surface of a component at a location of a worn seal surface;
- depositing a plurality of beads of seal material within the groove by laser cladding;
- and
- machining the plurality of beads of seal material to form a remanufactured seal surface that is generally flush with the interfacing surface of the component, the seal material being metallurgically bonded to the component.
