The fatigue strength and life of important parts in some aeroengines and their stability are determined not only by the internal material performance of the parts, but also by the quality of the processd surface or the quality of the surface integrity indicators, the process can reduce the fatigue life, but also can improve the fatigue life. Therefore, the study of the impact of different processing processes on the surface integrity of high-temperature alloys will be of great significance to the improvement of the life of aero engines.
