Abstract

The main object of this paper is to determine experimentally the effect of electrical current flow on the coefficient of friction between two dry rubbing surfaces. 
The tests were performed utilizing a pin-disc machine (Tribometer) with a pin having a diameter of 6 mm and 200 mm diameter disc. The current was be varied from 0 to 8 amperes with a constant potential difference of 12 volts. 
The coefficient of friction was calculated, at different loading and electrical current, based on the measured friction force. The measurement was carried out via strain 
gauge and FFT analyzer. 
A parametric study was carried out to highlight the effect of material, velocity and load on the coefficient of friction with the electrical current flow. Three sets of materials were used; steel-steel, copper-copper and aluminum-aluminum. Sliding velocity was increased up to 700 r.p.m., while the load changed from 1 to 8 Newton. 
As a result of this investigation, it was found that the coefficient of friction is depending strongly on the electrical current flow at all operating conditions.
