Study on Surface Modification of Pure Magnesium and Magnesium Alloy with High Current Pulsed Electron Beam

摘要

Pure magnesium and AZ31B magnesium alloy were irradiated by a high current pulsed electron beam (HCPEB) device with pulse times 10, 15 and 20 respectively. The microstructure changes of the surface and modified layer after HCPEB treatment were investigated, and the evolution of temperature field during the electron beam modification process was numerically simulated based on experimental and theories. Numerical simulation analysis is close to experimental results and the special surface morphology arising from treatment is interpreted.
