Abstract
This paper reports the effect of elements C, Cu, Ni and P on the diffusion bonding strength of iron-based green compacts during sintering.
As the result, it has been clarified that the material selections for assembled compacts should be based on the difference of thermal expansion curves of both materials during sintering, and that the additive elements which show large diffusion coefficient into iron should be chosen.
Among the above mentioned elements, C is the most effective and Ni is the least effective.
