Low‐plasticity burnishing (LPB) has been widely used in various industries. In the LPB process, when the ball moves on the material surface, plastic deformation or cold working occurs in the burnished region. Through this process, not only can LPB improve the surface integrity of metallic material components by replacing polishing in some situations, but it can also improve fatigue performance thanks to the low work hardening and the beneficial compressive residual stress (CRS). So far, extensive research has demonstrated the influence of the LPB process on surface integrity and service performance of different metallic materials, such as titanium alloys, aluminum alloys, magnesium alloys, nickel‐based superalloys, stainless steels, and carbon steels. Recent years have witnessed many innovative LPB processes and novel applications. Herein, the working principle of the LPB process is first restated. Following that, how LPB strengthens the material surface and thereby influences the mechanical performance, including the surface quality, residual stress, microstructure, microhardness, fatigue, and wear performance, is reviewed. Furthermore, the difference of surface‐strengthening effect among LPB and other surface mechanical strengthening processes is compared. Finally, the current challenges to LPB are discussed and some suggestions on its development directions are put forward.

In order to enhance the corrosion behavior of Ti6Al4V, a MAO coating was prepared on the surface refined by ultrasonic cold forging technology (UCFT). The surface roughness value and the grain were evaluated by atomic force microscope (AFM) and transmission electron microscope (TEM). The microstructure and phase component of the coated samples were analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The corrosion behavior of all the samples was examined by potentiodynamic polarization and electrode impedance spectroscopy (EIS) tests in a 3.5% NaCl solution. The results show that UCFT can reduce the surface roughness value and refine the grains. The micro-pore size of the UCFT-MAO sample is smaller and the pore number is less than those of MAO sample. The thickness of the coated sample is about 10 m. The UCFT-MAO sample possesses the highest micro-hardness among all the samples. The UCFT-MAO sample has the best corrosion resistance with the lowest corrosion current density and the highest electrochemical impedance, which is attributed to UCFT pretreatment prior to MAO process on titanium alloys. The influence of UCFT on the corrosion process and corrosion mechanism is discussed.

Many aviation accidents are caused by the failure of aircraft engine components, and engine blades are especially vulnerable to high‐cycle fatigue fracture in severe working environments as well as to impact damage caused by foreign objects. To address this problem, the United States took the lead and has been successful in implementing laser shock peening (LSP) as a surface treatment for aircraft engine components to enhance their fatigue performance. This review provides an overview of the development of LSP for use in treating aircraft engine components over the past three decades, with a brief introduction to the development of high‐energy pulsed lasers for LSP. A particular focus of this review is on the limitations and challenges associated with the application of LSP for treating critical aircraft engine components. It is hoped that this review serves as a reference for future research and development that can lead to better performance of these components.
