In this study, we investigated the mechanical properties of AZ31B Mg alloy before and after laser shock peening (LSP). The hardness of the AZ31B Mg alloy increased from 57 HV to 69 HV after LSP. The yield strength increased from 128 MPa to 152 MPa. Wear resistance was significantly improved after LSP. Immersion testing showed that LSP did not significantly increase the element release and weight loss in simulated body fluid. We have demonstrated that LSP is an effective way to improve the mechanical properties of the AZ31B Mg alloy.

Sbf Solution

The influences of different laser power density in LSP (laser shock peening) on the corrosion performance of biocompatible magnesium alloy ZK60 were researched via SBF (Simulated Body Fliud) immersion testing and electrochemical testing. Corrosion morphology and corrosion products were observed and analyzed using SEM (Scanning Electron Microscope) outfitted with EDS (Energy Dispersive Spectrometer) and XRD (X-ray Diffraction). Simultaneously, 3D morphology, surface roughness, residual stress, and microstructure were also characterized. Results reveal that the modified samples can obtain higher residual compressive stress, which can lead to lower degradation rates in SBF solution. In terms of the weight loss of the samples, corrosion resistance increased by 52.1% maximally. The corrosion potential of modified samples in the SBF solution positively shifted from −1.3884 V to −1.1094 V and the corrosion current density decreased by 13.2% at most. The anti-corrosion ability of ZK60 is significantly enhanced by the LSP process.

Abstract The effects of laser shock peening (LSP) on microstructure and properties of 32CrNi3MoVE steel are investigated. Laser shock peening experiment was undertaken using a laser system with the pulse-width of 15ns, 50% overlap rate, and pulse-energy of 7J. The microhardness, residual stress, microstructure, and wear resistance of the laser shock peening 32CrNi3MoVE steel samples were measured. The results show that the microhardness and residual compressive stress distribution is remarkably improved by LSP. High-density dislocations are generated and the width of the martensite grains is reduced to a certain extent, indicating the phenomenon of grain compression. The friction coefficient and wear rate of the material reduces so that the wear resistance is correspondingly improved. The wear mechanism of the untreated sample is abrasive wear and adhesive wear, the wear mechanism of the treated samples is abrasive wear.
