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.

The relationship between the screen mesh and the theoretical and practical ink film thickness was analyzed based on the main influencing factors of the ink film thickness by screen printing. A calculation model for the ink thickness was established based on the screen under static and compressive deformation. The relation curve between the screen mesh and the ink film thickness was fitted and the suitable printing craft parameter was chosen to print two kinds of RFID tag antennas. The fluctuation of the antenna resistance was analyzed to demonstrate the reliability of the passive RFID tag antenna manufactured by screen printing technology.
