    摘要: A metal cladding process utilizing a feed material (66) formed as a hollow sheath (68) containing a powdered core (70) including powdered metal and powdered flux material. The powdered metal and flux may have overlapping mesh size ranges. The sheath may be an extrudable subset of elements of a desired superalloy cladding material, with the powdered metal and powdered flux materials complementing the sheath to form the desired superalloy material when melted. The powdered metal may include an excess of titanium to compensate for a reaction of titanium with oxygen or carbon dioxide in a shielding gas. Heat for melting may be provided by an energy beam (64) or by utilizing the feed material as an electrode in a cold metal arc welding torch (54).
