Abstract

Components are disclosed which include a first component section and a second component section joined to form a hollow structure defining a plenum having an interior surface, wherein the component sections each include mating ridges joined together along the length of the plenum, and a corrosion-resistant cladding layer including a corrosion-resistant material overlaying the interior surface of the plenum. In one embodiment, the component is a gas turbine combustor fuel manifold. A method of forming the components includes applying corrosion-resistant segments including a corrosion-resistant material to each of the surfaces of the component sections, and joining the component sections to form the component, wherein joining the component sections includes fusing the corrosion-resistant segments into the corrosion-resistant cladding layer, and joining the mating ridges of the component sections.
