Fretting corrosion is a complex phenomena and a variety of factors such as load, contact area, frequency, number of fretting cycles, extent of damage of the fretted zone, trapping of debris between the contacting surfaces, corrosivity of the medium, etc., will determine the fretting-corrosion behaviour. The present paper aims to develop a fretting-corrosion map of commercially pure Ti (CP-Ti) based on its fretting-corrosion behaviour in Ringer's solution under various combinations of load, frequency and number of fretting cycles. Based on the fretting-corrosion behaviour and restoration ability, a fretting-corrosion map of CP-Ti in Ringer's solution is developed for the first time. The fretting-corrosion map of CP-Ti in Ringer's solution enables identification of various regimes depending on the nature of predominant phenomenon for a given set of conditions. Since fretting corrosion is the dominant phenomenon at lesser duration of fretting at 5 and 10 Hz for a load of 3 and 5 N, the safer use of CP-Ti, particularly for hip and knee implants, is a major concern.
