Abstract: Cladding and remanufacturing a machine component includes directing cleaning and welding beams split from an incident laser beam toward the machine component, and moving the machine component relative the cleaning and welding beams such that the welding beam trails behind the cleaning beam along a common travel path. A surface of the machine component is decontaminated by the cleaning beam, while a cladding material is melted via the welding beam such that upon solidifying the cladding material forms a coating metallurgically bonded to base material and previously deposited cladding material of the machine component.

Abstract: A cladding composition is configured for use in a laser cladding process to remanufacture the wear surfaces of machine components that require a significant degree of hardness. The cladding composition can be provided in a powdered form and can include molybdenum (Mo), tungsten (W), cobalt (Co), nickel (Ni), carbon (C), and manganese (Mn) with the balance of the composition being iron. The cladding composition, after melting and solidifying on the wear surface, can from a solid cladding layer having a hardness of 50 or greater as measured on the Rockwell C scale while maintain a significant degree of fracture toughness.
