Abstract
This paper describes an apparatus used to investigate the temperature variable in fretting. Observations have been made on the nature of the wear, its appearance, and its extent in two atmospheres—air and argon. In argon, the wear is adhesive in nature and has been shown to be influenced by a change of material properties with temperature. With an air environment, the adherence and stability of the oxide product is temperature-dependent, thus affecting the wear rate. From a consideration of wear scar parameters it is shown that abrasion by α-Fe2O3 debris is not the main cause of fretting wear.
