Electrical contact resistance and its relationship to …

Studies have been made of the electrical resistance at the contact between a silicon carbide indenter and various metals. It has been found that reproducible results can be obtained if the contact under load is subjected to a low-energy condenser discharge prior to the measurement of the resistance. After this pre-test operation, the electrical resistance is inversely proportional to the
