Model of the physical–chemical interaction of EP202 alloy with a copper–silver brazing alloy and the strength of the bond at the interface

Abstract

A model of the interaction of a complexly alloyed alloy based on Ni–Cr with a copper–silver brazing alloy is developed and used for estimating the selective affinity of the individual elements of the alloy, in particular Ni, with the elements of the brazing alloy on the atomic level.
