LASER CLADDING MECHANICAL FACE SEALS

摘要

A method of producing a mechanical face seal, the method including a step of obtaining a cast or wrought substrate part having an inner diameter, outer diameter, and a planar surface. The method may include an exposing step to expose the planar surface to a laser. The method may further include a supply step to supply a coating material to a location at or near the laser on the planar surface in order for the coating material to form a metallurgical bond with the substrate part.

1. A method of producing a tightly dimensionally controlled mechanical face seal, the method comprising:
forming a cast or wrought substrate part, the substrate part having an inner diameter, an outer diameter, and a planar surface extending between the inner diameter and the outer diameter; supplying a coating material to a top layer of the planar surface, the coating material comprising at least one of a Fe-based alloy, a Ni-based alloy, and a Co-based alloy; and exposing a laser to at least the planar surface, the exposing including tracing the top layer of the planar surface to melt a top surface of the substrate part and the coating material together to form a metallurgical bond.
