Abstract
The possibilities of changing the conductivity of surface films during electrolysis are studied. The results of experimental research into films on nickel contacts are presented. From a comparison of ellipsometric, X-ray diffraction, and Auger-spectrum measurements of nickel coating surfaces obtained from electrolytes with organic components, it is revealed that the structure and composition of the surface films undergo changes which result in a decrease in the contact resistance. This makes it possible to employ such films in low-current contacts instead of silver or silver-alloy coatings.
