Abstract
- Machined surface integrity is a comprehensive description of surface quality, which mainly includes the key indexes, such as surface micro-morphology, surface hardening, surface residual stress, and surface microstructure. It has a direct influence on the fatigue performance of specimens. Therefore, a lot of researches have been carried out in-depth, and many results are achieved. Based on the formation mechanism of surface integrity indexes, main achievements of influence mechanism of surface integrity on fatigue behavior of metal specimens are presented and analyzed, and the internal relationship and application range of the mechanisms are clarified. It is further presented that the extremely important factor of surface integrity affecting fatigue performance of specimens is the micro-plastic strain of machined surface, and the contents that need to be further improved in the basic theory of anti-fatigue machining are analyzed. Meanwhile, it is pointed out that establishing a comprehensive model of the influence of surface integrity on fatigue performance based on surface micro-morphology and surface plastic deformation is a focus point, which provides a reference for the further researchers and promotes the application of anti-fatigue machining technology.
