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 conducting wall in micro-tube preheats the inlet mixture by axial heat transfer. The existence of conducting wall will help to reach full reaction in the micro-tube. As the inlet velocity increases, both the existence of the surface catalytic combustion and the gas phase combustion become the limiting factors on combustion. Wall material and equivalence ratio of hydrogen/air mixture have important influence on catalytic combustion of hydrogen.
