Wear and corrosion performance of AZ31B magnesium alloy strengthened by combination of surface mechanical attrition treatment and laser shock peening
The poor wear and corrosion resistance of magnesium alloys limits their applications in structural components. In this study, the effect of surface mechanical attrition treatment (SMAT), laser shock peening (LSP), and the combination of the two techniques on the wear and corrosion performance of the AZ31B magnesium alloy was investigated. The results demonstrate that both SMAT and LSP refine the surface grains of the AZ31B magnesium alloy. Moreover, SMAT facilitates the formation of surface nanocrystallization, which is preserved following the application of LSP. The wear rate of the specimen subjected to LSP following SMAT treatment is 79.8% lower than that of the bare specimen under room temperature dry friction conditions. The corrosion rate is 79.8% lower than that of the bare specimen in a 3.5% NaCl solution. The specimen subjected to LSP following SMAT treatment exhibits an enhanced anti-wear property and corrosion resistance. The combination of SMAT and LSP not only retains the surface hardening effect of SMAT but also has the advantages of a deep compressive stress layer and hardening layer of LSP, thus more effectively improving the surface properties of AZ31B magnesium alloys.
