1. A method comprising:
providing a substrate comprising an aluminum alloy and a first surface; machining the first surface to define a cavity; processing the cavity to remove oxidation of the aluminum-nickel alloy; cladding the substrate with a coating via laser hard facing the substrate wherein the laser hard facing comprises: providing a metallic material onto the first surface; providing a laser and applying the focal point of a laser beam on the metallic material; flowing a shielding gas around the laser beam; melting the metallic material via the laser beam such that a melt pool, the coating, and dilution layer are formed on the first surface; fine machining the coating; and polishing the coating. |
