Abstract:The deep rolling strengthening process, as one of the mechanical surface treatment technologies, can effectively improve the fatigue performance, wear resistance, corrosion resistance and damage tolerance of materials, and has been used in surface modification of aeroengine blades. This article first introduces the basic principle and advantages of the deep rolling strengthening process. Considering the important influence of the evolution of surface characteristics on fatigue performance, a growing number of scholars attach increasing importance to this problem and extensive studies have been carried out. We comprehensively review the fatigue evolution and anti-fatigue mechanism of the surface characteristics (residual stress, microhardness and microstructure), and the progress in fatigue life prediction of the deep rolling strengthening process. Moreover, a horizontal comparative analysis with the current research of other technologies is performed and the deficiencies in the current research of the deep rolling strengthening process are summarized. Finally, future research and development direction of the deep rolling strengthening process are prospected.
Keywords:deep rolling  surface characteristics  residual stress  microstructure  microhardness  fatigue evolution  anti-fatigue mechanism
