Wire resistance method for measuring the corrosion of copper by lubricating fluids

A new method for monitoring the corrosion of copper by lubricating fluid additives through the measurement of the electrical resistance of copper wires is presented. The effect of base oil and lubricant additive components upon the corrosion rate of copper is discussed. The information on corrosion generated by this method provides details of the corrosion processes that are not obtained from traditional corrosion tests and insight as to how to formulate oils to better protect copper and copper alloys.
