A PROCESS ON DIFFUSION BONDING BETWEEN FE-BASED AND CU-BASED MATERIALS IN SEMI-SOLID REGION

摘要

Purpose: a kind of diffusion bonding method for a kind of Fe alloys and an Albatra metal is arranged to simplify a process and reduces two alloys that a cost is diffusely incorporated in half solid-state areas. Construction: in order to diffusely combine a kind of Fe alloys and an Albatra metal, the surface of copper alloy reduces and Fe alloys is used to assemble. Here, the fusing point of copper alloy is lower than Fe alloys. The alloy of assembling is packed into a stove and controls under a vacuum, nitrogen, argon gas or complex gas atmosphere. Then, 1060deg. is arrived 750The semi-solid temperature of C, alloy is heated and is maintained at the semisolid of regularly time for diffusion bond. After that, the cooled air of bonding alloy or in a furnace.
