Component, gas turbine component and method of forming

A gas turbine component, comprising:

• a first component section and a second component section joined to form a combustor fuel manifold, wherein:
• the combustor fuel manifold is an annulus;
• the combustor fuel manifold defines a plenum including an interior surface, a width and a length, the length being greater than the width and extending along a circumferential path of the combustor fuel manifold;
• the first component section includes a first substrate material and the second component section includes a second substrate material;
• the first component section includes a first mating ridge and a second mating ridge extending radially outward relative to the circumferential path;
• the second component section includes a third mating ridge and a fourth mating ridge extending radially inward relative to the circumferential path;
• the first mating ridge is joined to the third mating ridge along the length of the plenum;
• and
• the second mating ridge is joined to the fourth mating ridge along the length of the plenum;
• and
• a corrosion-resistant cladding layer including a corrosion-resistant material,
• wherein the corrosion-resistant cladding layer overlays the interior surface of the plenum and the corrosion-resistant cladding layer includes a first corrosion-resistant segment overlaying the first component section fused to a second corrosion-resistant segment overlaying the second component section.

A method of forming a component, comprising:

• providing a first component section and a second component section, wherein:
