Experimental results obtained by the authors and results from the literature are summarized to provide a critical review of the effects of various factors on fretting wear. These factors fall into three broad categories: (1) contact conditions, (2) environmental conditions, and (3) material properties and behavior. Contact load, amplitude and frequency of motion, and contact geometry are included under contact conditions. Environmental conditions include atmosphere, relative humidity, and temperature. The importance of material properties is discussed on the basis of how material properties interact with other factors during fretting. Individually, the effect of contact load, fretting amplitude, temperature, and atmosphere have been fairly well explored for a limited number of materials (mostly mild steel). More work is clearly needed to provide basic understanding of the effects of contact geometry and relative humidity and the interaction of various fretting parameters. A more comprehensive number of materials should be studied to clarify material property effects.
