They are FF testing methods, surface treatment technique, evaluation of the properties of surface modification layer, coating induced embrittlement, selection of coating materials, effects of SP and other surface modification on fretting fatigue resistance . A new coating technology combined with shot peening is proved in improving FFR of titanium alloy. The relation between fretting wear and fretting fatigue mechanism of titanium alloy are discussed on the basis of the experimental results. The main contributions are as follows:(1) Shot peening is the most efficient way in improving fretting fatigue resistance of titanium alloys. Working hardening, roughening and compressive residual stress are involved in the shot peened surface.
