“…In addition, some micro-cracks may also be formed after the SP treatment (Zhou et al, 2018), which could be the diffusion path of ions and accelerate the corrosion of the steel. Prabhakaran et al (2018) and Guan et al (2022) suggested that LSP treatment could significantly enhance the pitting corrosion resistance of 304 stainless steel in NaCl solution (Figure 11), but no difference in uniform corrosion. LSPinduced surface grain refinement is one factor for the improvement of pitting resistance (Sun et al, 2009).…”

“…LSP-induced residual compressive stress is the other factor for enhancing pitting resistance. It helps minimize the microcracks between intermetallic and matrix steels (Guan et al , 2022) and suppress the penetration of Cl − through the passive film (Trdan and Grum, 2012). However, other investigations confirmed that a similar (Liu et al , 2019) or even worse (Guan et al , 2021) pitting resistance was obtained after the LSP treatment, which may be resulted from the increase in surface roughness as mentioned in Table 1.…”

Purpose This paper aims to review the effect of traditional shot peening (SP), laser shock peening (LSP) and water jet cavitation peening (WJP) on microstructure evolution and corrosion behavior of austenitic stainless steels 316L and 304. Design/methodology/approach The effect of SP, LSP and WJP on corrosion behavior of 316L and 304 were discussed in terms of surface peening–induced change in surface roughness, stress state and grain size. Findings Residual compressive stress and grain refinement were introduced after SP, LSP and WJP treatment in 316L and 304 stainless steels. Superior corrosion resistance can be obtained by WJP compared with SP and LSP. Originality/value The relationship between SP-, LSP- and WJP-induced change in microstructure and stress state and corrosion resistance was summarized.

“…Laser shock peening (LSP) is one of the most promising techniques for surface enhancement, and is widely used for improving the wearing quality, corrosion resistance and fatigue performance by inducing the beneficial compressive residual stress field and grain refinement in the processed materials [ 1 , 2 , 3 , 4 , 5 ]. In comparison with the conventional shot peening (SP) and ultrasonic shot peening (USP) [ 6 , 7 , 8 ], LSP not only has good operating controllability and geometric adaptability, but also can produce a deeper compressive residual stress field and the better preservation of surface roughness [ 9 ].…”

Laser shock peening (LSP) is an innovative and promising surface strengthening technique of metallic materials. The LSP-induced plastic deformation, the compressive residual stresses and the microstructure evolution are essentially attributed to the laser plasma-induced shock wave. A three-dimensional finite element model in conjunction with the dislocation density-based constitutive model was developed to simulate the LSP of pure Al correlating with the LSP-induced shock wave, and the predicted in-depth residual stresses are in reasonable agreement with the experiment results. The LSP-induced shock wave associated with the laser spot diameter of 8.0 mm propagates in the form of the plane wave, and attenuates exponentially. At the same time, the propagation and attenuation of the LSP-induced shock wave associated with the laser spot diameter of 0.8 mm are in the form of the spherical wave. The reflection of the LSP-induced shock wave at the bottom surface of the target model increases the plastic deformation of the target bottom, resulting in the increase of dislocation density and the decrease of dislocation cell size accordingly. Reducing the target thickness can significantly increase the reflection times of the LSP-induced shock wave at the bottom and top surfaces of the target model, which is considered to be conductive to the generation of the compressive residual stress field and grain refinement.

“…At present, there are few studies on the LSP of steel mold surfaces, and mostly they focus on improving the wear and fatigue resistance of aerospace materials such as titanium alloys and aluminum alloys [ 11 , 12 , 13 , 14 ]. Hepeng Zhang [ 15 ] studied the effect of LSP on the microstructure gradient of TC titanium alloy and proposed a set of predictive life integration methods for the use of laser strengthening technology.…”

Effect of Laser Quenching-Shock Peening Strengthening on the Microstructure and Mechanical Properties of Cr12MoV Steel

The automobile covering parts mold is a key piece of equipment in the automobile industry, and its drawbead is the core element that affects the life of the mold and the quality of the parts made. Due to the complex structure of the mold cavity for covering parts, there exist differences between material flow characteristics, load conditions, stress strain, failure forms and so on in the surface of different parts of its drawbead and the different directions of the same part of the drawbead, thus putting forward new requirements for material strengthening. For the differentiated lose efficacy forms of the dangerous end faces of the tension bars, this study carried out research into the effect of laser quenching–shock peening strengthening (LQ-LSP) on the organization, plastic deformation resistance and wear resistance of Cr12MoV steel. It was shown that the microhardness (722.30 HV) and residual stress (−383.84 MPa) of the specimens were further enhanced after laser quenching–shock peening composite strengthening. The residual austenite content of the specimen was reduced to 0.8%, and the eutectic carbide distribution morphology was improved. After three rounds of laser composite peening, the specimens had the smallest displacement of the nanoindentation load–depth curve, which exhibited the greatest nanohardness (20.0 Pa) and modulus of elasticity (565.25 Pa), while reducing the coefficient of friction (0.61) and surface roughness (0.152 Ra). The smooth and flat surface of the specimen with shallow and narrow plow grooves improved the resistance of Cr12MoV steel to plastic deformation and wear.
