Abstract

Fretting corrosion of a tin-plated copper alloy was investigated over the temperature range up to 110 degrees C using a dimple-flat contact configuration. Results, based on contact resistance (CR) characteristics and scanning electron microscopy examination, revealed that room temperature corrosion results are not valid at elevated temperatures. Specifically, the corrosion rate as well as the statistical scatter of the CR characteristics have a strong temperature dependence. For temperatures of 60-85 degrees C, the Cr rose several times faster, while, outside this temperature range, the corrosion rate was significantly slower.<>
