“…During the corrosion process, the large grains and the surrounding nanograins will form a galvanic cell and accelerate the dissolution of the large grains, which act as the anodes. As a result, the corrosion rate gradually increased with an increase in the immersion time [45]. The corrosion rate of Mg alloys in the SBF solution with a passivation environment increased with an increase in grain size [46].…”

With the help of supersonic fine particle bombardment technology, a gradient nanostructure with a certain layer depth was constructed on the surface of an Mg-1.8Zn-0.5Zr-1.5Gd biological magnesium alloy. The effects of bombardment time on the microstructure, mechanical properties, and corrosion resistance of the gradient nanostructure were investigated. The results showed that the layer depth and surface roughness of the gradient nanostructures increased with an increase in the bombardment time, and the corresponding mechanical properties and corrosion resistance first increased and then decreased with an extension of the bombardment time. When the bombardment time was 30 s, the alloy had good mechanical properties and corrosion resistance. Its tensile strength, yield strength, elongation, and static corrosion rate were 299.1 ± 2.2 MPa, 264.4 ± 1.5 MPa, 36.8 ± 1.3 %, and 0.307 ± 0.015 mm y −1 , respectively. The results of the 120-h immersion experiment in simulated human body fluids showed that the average corrosion rate of the alloy first decreased, then increased, and finally decreased with an extension of the immersion time and finally tended to stabilize.

“…The DCs subdivide into sub-grains with a further increase in the strain. In some cases, the formation of nanocrystalline grains is also possible [104,108,109]. Figure 10 shows the grain refinement mechanism of laser-peened Ti–6Al–4V alloy.…”

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.
