“…A recent study showed that the USRP was able to prevent the corrosion of an austenitic stainless steel surface due to a stable passive film and its small surface roughness [19]. The residual compressive stress induced by plastic deformation during the USRP played a beneficial role in the resistance to corrosion [20]. It was found that the hydrophobicity of a surface modified with the USRP was enhanced in our previous study.…”

“…Severe plastic deformation was able to result in a high surface residual compressive stress during the USRP treatment. The residual compressive stress was able to inhibit the metastable pitting in nucleation [20]. The residual compressive stress made the passive film more robust and compact because of the slightly lower interatomic distances in the underlying compressively stressed metal lattice [25].…”

This research aimed to investigate the effects of an ultrasonic surface rolling process (USRP) on the deposition behaviors in CaCO3 crystallization fouling for 304 stainless steel (304SS). The microstructure, surface morphology, and hydrophobic properties of the modified layer were characterized with optical microscopy, a roughness profile measurement instrument, and a contact angle measurement instrument. The corrosion and fouling behaviors of different surfaces were studied in simulated cooling water. The polarization curves and electrochemical impedance spectroscopy (EIS) were used to evaluate the electrochemical properties. The results showed that USRP-treated surfaces had better anti-corrosion and anti-fouling performance. The improvement in anti-fouling performance was attributed to the weakening of peaks and valleys, the reduction of surface defects, and the improvement of corrosion resistance.

“…It helps minimize the microcracks between intermetallic and matrix steels (Guan et al, 2022) and suppress the penetration of Cl À 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. Compared with SP and LSP, WJP is a surface strengthening technology introducing lower materials damage and middle magnitude residual compressive stress as discussed in Section 3.1.…”

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.

“…Structural steels such as 316, 321, UNS S44600, 17–4 PH steels, 253 MA and P91 steels were laser peened and significantly improved hardness. SS 316 steel showed a hardness of around 7 GPa compared to 4 GPa of unpeened samples [119]. Karthik et al investigation on AISI 321 [120] 17–4 PH steels [121] showed an increase in hardness and work hardening after laser peeing.…”

Laser shock peening (LSP) is a unique and efficient surface modification technique that surface engineers have commonly adopted to tailor metallic materials' surface and subsurface properties. The primary goal of this review paper is to highlight LSP as a surface modification technique for materials used in aeroengine, as this further ameliorates the commercialization of LSP in aeroengine sectors. The recent research articles focused on the application of LSP to improve the surface characteristics (i.e. surface residual stresses, hardness) and to resist the corresponding service challenges (i.e. fatigue, wear) of the aeroengine metallic material have been reviewed. In addition, a brief explanation of LSP and its controlling parameters is included. From the aeroengines perspective, challenges and future aspects for improving LSP application and commercialization are summarised based on the authors' experience and published literature.
