Many studies of fretting corrosion and wear are conducted on production machinery or on fatigue testing devices. Such devices often rely on elastic strains in loaded members as the source of the fretting motion. This makes measurement and control of slip amplitude and frequency and of normal force difficult. Assessment of the damage is also often difficult.
This paper discusses problems in studying fretting phenomena and describes the use of a slider-crank tester that allows control of most fretting variables, including slip amplitude. Fretting resistance test data are presented on a variety of coatings and metal couples. Recommendations are made on the use of various metal couples and selected surface treatments.
