COMPOSITE WIRE FOR BUILD-UP WELDING TO SURFACE OF TI BASE MATERIAL

摘要

PURPOSE: To provide the composite wire for build-up welding which can stably feed a filler metal by using the composite wire and with which a build-up layer having high joinability to a Ti base material and excellent wear resistance and heat resistance is obtainable and which is inexpensive and is suitable to the surface of Ti base material. ;CONSTITUTION: This composite wire for build-up welding to the surface of the Ti base material is constituted by packing a core material consisting of the Ti base material into the hollow of a shell material consisting of a Cu material. The composite wire contains, by the total weight of the composite wire, 10 to 70wt.% Cu, 0.1 to 6% Al and 0.1 to 4% V and the balance Ti. Then, crack does not arise and the alloyed layer having the high joinability to the Ti base material and the excellent wear resistance and heat resistance is stably and inexpensively formed if the composite wire formed by packing the core material consisting of the Ti base material into the shell material made of the Cu is used.;COPYRIGHT: (C)1994,JPO&Japio
