Shot peening is a dynamically developing surface treatment used to improve the surface properties modified by tool, impact, microblasting, or shot action. This paper reviews the basic information regarding shot peening methods. The peening processes and effects of the shot peening and cavitation peening treatments on the surface layer properties of metallic components are analysed. Moreover, the effects of peening on the operational performance of metallic materials are summarized. Shot peening is generally applied to reduce the surface roughness, increase the hardness, and densify the surface layer microstructure, which leads to work hardening effects. In addition, the residual compressive stresses introduced into the material have a beneficial effect on the performance of the surface layer. Therefore, peening can be beneficial for metallic structures prone to fatigue, corrosion, and wear. Recently, cavitation peening has been increasingly developed. This review paper suggests that most research on cavitation peening omits the treatment of additively manufactured metallic materials. Furthermore, no published studies combine shot peening and cavitation peening in one hybrid process, which could synthesize the benefits of both peening processes. Moreover, there is a need to investigate the effects of peening, especially cavitation peening and hybrid peening, on the anti-wear and corrosion performance of additively manufactured metallic materials. Therefore, the literature gap leading to the scope of future work is also included.

“…In the case of a submerged jet, i.e., a cavitating jet in water, treating outer surfaces of tanks and/or pipelines is difficult. Soyama realized "a cavitating jet in air" by injecting a high-speed water jet into a low speed water jet, which was injected into air without a water-filled chamber, and demonstrated the introduction of compressive residual stress into a metallic surface and the resulting improvement of fatigue strength of stainless steel [27,28] and nitrocarburized steel [29]. The cavitating jet in air research has been followed by Marcon et al [30,31].…”

“…Improvements in the fatigue strength of metallic materials, such as aluminum alloy [4,117,143], carbonized steel [12], nitrocarburized steel [29], stainless steel [28], silicon manganese steel [32], and titanium alloy [38], by cavitation peening were reported. Additive manufactured titanium alloy was also tested in comparison with shot peening and laser peening, and the fatigue strength was improved by cavitation peening by about two times in comparison with non-peened [44].…”

The most popular surface modification technology used to enhance the mechanical properties of metallic materials is shot peening. Shot peening improves fatigue life and strength by introducing local plastic deformation pits. However, the pits increase surface roughness, which is a disadvantage for fatigue properties. Recently, cavitation peening, in which cavitation bubble collapse impacts are used, has been developed as an advanced surface modification technology. The advantage of cavitation peening is the lesser increase in surface roughness compared with shot peening, as no solid collisions occur in cavitation peening. In conventional cavitation peening, cavitation is generated by injecting a high-speed water jet into water. However, cavitation peening is different from water jet peening, in which water column impacts are used. In the present review, to avoid confusing cavitation peening and water jet peening, fundamentals and mechanisms of cavitation peening are described in comparison to water jet peening, and the effects and applications of cavitation peening are reviewed compared with the other peening methods.
