摘要：

The influence of the dose rate of N2+ on the microstructure in 316L stainless steel after ion implantation has been studied. Nitrogen implantation was performed with dose rates in the range 5 X 10(16)-1.5 X 10(17) N2+ ions cm-2, accelerator potential of 80 keV, current density of 1 muA cm-2 and sample's temperature maintained below 70-degrees-C. It is shown, by grazing angle X-ray diffraction (GXRD), glow discharge optical spectroscopy (GDOS) and conversion electron Mossbauer spectroscopy (CEMS), that the nitrogen distribution is not homogeneous and partitioned between two austenitic phases and the CrN nitride. The conditions of implantation on this partitioning are discussed in order to optimize the microstructure for corrosion resistance.
