Influence of Ion Current Density on the Surface Morphology of AZ31 Magnesium Alloy Irradiated by High-Intensity Pulsed Ion Beam

Abstract:

HIPIB irradiation into AZ31 magnesium alloy is performed at ion current density of 100-300 A/cm² with 1 shot. The surface morphologies and surface profiles of the irradiated AZ31 magnesium alloy samples are characterized by scanning electron microscopy (SEM) and profilometer, respectively. It is found that HIPIB irradiation leads to the formation of crater in local region of irradiated samples, and crater density increases with increasing ion current density. Both the surface roughness that reflects the vertical wave of surface profile and the mean spacing of surface profile irregularities that reflects the horizontal wave of surface profile increase as ion current density increases. These results are in agreement with the SEM observation on the irradiated surface.
