摘要

The fretting fatigue resistance (FFR) of materials is related to composition, microstructure, and mechanical properties of the materials. The relationship is different for different materials. In order to further investigate the influence of material factors on FFR, the FFR of two heat-resistant steels with different tension strength and two titanium alloys with different microstructure was compared. Fretting pad material on FFR was also studied in the present paper. The results show that the FFR of Ti6Al4V and Cr17Ni2 with high tension and plain fatigue strength is higher than that of Ti5Al2.5Sn and 1Cr11Ni2W2MoV respectively. Which means that FFR is predominantly determined by tension and plain fatigue strength for the materials having same or similar microstructure. In the situation of using a hard fretting fad, fretting fatigue crack initiates easily and the fretting fatigue life is low. Under this condition, shot peening is remarkable effective for improving FFR of materials.
