硬质合金与工具钢的扩散焊接

The Bonding by Diffusion of the Hard Metal and Alloy Tool Steel

摘要: 探讨了过渡族金属作为过渡层金属时,其焊接工艺条件对硬质合金和合金工具钢在扩散焊接时,对结合部的强度的影响。同时还研究了过渡层金属的种类、厚度及线膨胀系数对接合强度的影响。

Abstract: The transition-metals must be used in order to improve the strength of the welding places when hard metal and alloy tool steel are bonded by diffusion. This paper studies the technology which influences the welding strength when Co and Ni are used as the transition-metale. The catalogue of transition-metals, thickness and the thermal expansion coefficient which influence the strength of the bonded places are studied as well.
