抄録

The influence of the nitrogen ion implantation on the corrosion resistance of magnesium has been studied. The nitrogen solid solution and Mg₃N₂ were detected by the grazing incidence X-ray diffraction analysis. TEM observations revealed the morphology of Mg₃N₂ and cavities in magnesium matrix. Anodic polarization measurements showed that implantation with 1×10²¹ N₂⁺⁄m² at 150 keV greatly reduce the current density at all applied voltage. The higher accelerating voltage showed better corrosion resistance. The amount of Mg₃N₂ was increased with increasing dose resulting in the degradation of corrosion resistance. The corrosion resistance of implanted specimen was also degraded by annealing.
