PROBLEM TO BE SOLVED: To provide a component, a turbine component, and a method of forming them.SOLUTION: A component (100) includes a first component section (102) and a second component section (104) that are joined to form a hollow structure (106) defining a plenum (108) having an interior surface (110). The component sections each include mating ridges (120, 122, 124, 126) joined together along a length (114) of the plenum, and a corrosion-resistant cladding layer (128) including a corrosion-resistant material (130) overlaying the interior surface of the plenum. In one embodiment, the component is a gas turbine combustor fuel manifold. A method of forming the component 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, where the joining step includes fusing the corrosion-resistant segments into the corrosion-resistant cladding layer, and joining the mating ridges of the component sections.SELECTED DRAWING: Figure 1 【課題】部品、タービン部品並びにそれらの形成方法を提供する。【解決手段】部品（１００）は第１の部品セクション（１０２）及び第２の部品セクション（１０４）を含んでいて、それらは接合されて、内側表面（１１０）を有するプレナム（１０８）を画成する中空構造（１０６）を形成する。部品セクションは各々、プレナムの長さ（１１４）に沿って接合される係合隆起部（１２０，１２２，１２４，１２６）と、プレナムの内側表面上に設けられた耐食材料（１３０）を含む耐食クラッド層（１２８）とを含む。部品の一例は、ガスタービン燃焼器の燃料マニホールドである。部品の形成方法は、耐食材料を含む耐食セグメントを部品セクションの表面の各々に施工し、部品セクションを接合して部品を形成することを含んでおり、接合ステップは、耐食セグメントを溶融して耐食クラッド層とし、部品セクションの係合隆起部を接合することとを含む。【選択図】図１
