Zusammenfassung:	PROBLEM TO BE SOLVED: To make a sealing property of a mother material and a repair material even in a condition that oxides inside a crack part is not removed, or is partly remained. SOLUTION: Under a condition that oxides 3 exist inside a crack part 3, a repair material 4 made of a brazing material obtained by adding melting-point lowering elements such as B and Si to components or compositions similar to a brazing material of a nickel base alloy or a base material of a gas turbine part is put on a top of a crack part 2. Under a vacuum condition, the repair material is molten by heating the base material 1 and the repair material 4 at a temperature slightly higher than the melting temperature of the repair material, and the oxides 3 in the crack part 2 is separated from a repairing face. After the repair material 4 fills inside of the crack part 2, and is metallically jointed with the base material 1, and then cooled. COPYRIGHT: (C)2005,JPO&NCIPI
