Comparative Analysis of the Influence of Striction Resistance and Disturbing Pellicles on the Contact Resistance

The present paper presents a comparative study on the influence of the two components of contact resistance, namely the tensile strength and the resistance of disturbing pellicles. The study was performed by repetitively simulating the closing and opening of a contact system that operates [runs] idle, respectively under nominal load, following the structural changes of the contacts, especially the evolution of the resistance of disturbing pellicles. Changes in the contact surface were studied using an AFM microscope.
