LIQUID PHASE DIFFUSION BONDING OF DISSIMILAR METALS

摘要

PROBLEM TO BE SOLVED: To provide improved liquid phase diffusion bonding of dissimilar metals, more particularly, of copper or a copper alloy to a non-copper alloy. SOLUTION: In the method for forming a component, a braze material is assembled between first and second wall portions to form a sandwich. The first wall portion consists essentially of copper or a copper-based alloy. The second wall portion comprises at least one non-copper-based alloy. The sandwich is heated. The heating melts the braze material to cause a liquid phase diffusion bonding of at least a portion of the first wall portion to the second wall portion. COPYRIGHT: (C)2007,JPO&INPIT
