- Fretting can cause the contact resistance of electrical components to become unstable. Fretting originates in vibration, mechanical shock, thermal fluctuations, and magnetic forces to which conductors are subjected. Gold is a preferred contact material because it is inert and therefore has a contact resistance which remains nearly constant during fretting. However, insulating oxide films appear at the interface of base metal contacts and gold-coated base metal contacts when the gold wears out. Platinum group metal contacts catalyze the formation of frictional polymers from organic materials, such as air pollutants, in their vicinity. Thus, fretting corrosion and friction polymerization can increase contact resistance and thereby cause electrical failure.
