This paper studies the processes occurring on the phase obundaries between tungsten (molybdenum) and copper (silver) in the presence of nickel or cobalt to deliverately influence the microstructure of contacts, with the object of improving their operational characteristics. It is shown that the nature of the interaction between the materials of the rod, i.e., tungsten (molybdenum), and of the interlayer, i.e., nickel (cobalt) depends on the nature of the outer layer (copper or silver). This interaction determines the final microstructure, the distribution of the phase components, and the formation of new phases in real pseudoalloys.
