A Phenomological Approach to Fretting Corrosion

An analytical description of fretting corrosion is proposed wherein the volume of wear debris either removed from the sliding interface or retained within these areas, is represented as a fraction of the freshly-produced debris in each fretting pass. In the proposed model, the volumes of removed debris and retained debris are tallied separately over each pass of a fretting sequence to yield a closed analytical expression relating these volumes to the number of passes. The paper provides examples of the adaptation of the proposed model to experimental fretting corrosion data in tin-tin electrical contacts.
