METHOD OF MANUFACTURING LINER FOR COMBUSTOR

摘要

PURPOSE: To obtain a joint part with a high temperature strength and excellent malleability by a method wherein an insert material made up of an Au foil and an Ni foil is inserted into a part as joint surface of a member and pressurized slightly and heated up to a target temperature in a vacuum or an inactive atmosphere to be held and joined. CONSTITUTION: A combustor for a gas turbine is provided with an outer cylinder 1, a combustor liner 2 set in the outer cylinder 1 and a tail cylinder 3 connected to the rear of the combustor liner 2 and the combustor liner 2 forms a combustion chamber. When a plurality of members worked in a shape of a semi-cylinder or a cylinder comprising an Ni and Fe based oxide scattered reinforced alloy are joined together, an Au foil and an Ni foil are heated and pressurized as insert material in a vacuum or an inactive atmosphere. The insert material is built by laminating the Au foil and the Ni foil with a thickness of 1-100μm and the Ni foil herein used is pure Ni or an alloy produced by adding Si to Ni at a rate of 1-5%. The Ni foil of the insert material is thinner than the Au foil.
