PROBLEM TO BE SOLVED: To provide a method for manufacturing a braze preform having a desired shape and durability. SOLUTION: The method for manufacturing the braze preform 52 comprises a step for preparing a mixture of metal powders of a brazing alloy and a binding agent, a step for forming the mixture into a preform 52 having the predetermined shape by dissolving the binding agent, a step for removing most of the binding agent from the preform 52, and a step for heating the preform 52 so as to remove a remainder of the binding agent from the preform and sinter the metal powders. The preform 52 may include wear-resistant material therein. The preform 52 can be used to form a braze joint between two metal components or to make a metal component having a wear-resistant film surface. COPYRIGHT: (C)2008,JPO&INPIT |
