As a result of the rotational sliding test by applying a fretting corrosion tester on a tin-plated mock contact, the electrical resistance is stable at a low level at the beginning but then is increasing slowly to a high level. It is found out that the smaller the contact force is and the larger the rotation angle is, the earlier the resistance will increase. Investigating the causes of the increase of the resistance by observing the fretting trace, it is expected that the resistance increases because the whole contact surface is covered with oxide particles.
