Annotation
Investigation results of the grain-boundary diffusion in Сu films with thin Ni coating and in Ni films with thin Cu coating by the low-temperature resistometric method are presented in this work. It is shown that during the coating deposition and thermal annealing the irreversible increase in the electrical resistance by the value from tenth parts to a few Ohms is observed. This is caused by the diffusion processes of coating atoms on the grain boundaries of base layers.
