摘要：

Nitrogen ion implantation of pure Fe and AISI 304 stainless steel to doses as high as 1 x 10(19) N2+/cm2 while the target is held at elevated temperatures between 100 and 600-degrees-C leads to layers of various N-containing phases as identified by conversion electron Mossbauer spectroscopy and X-ray diffraction. Very thick layers, compared to the ballistic implantation depth, containing gamma'-Fe4N can be produced by holding the Fe targets near 400-degrees-C while even thicker layers containing either epsilon-(Fe, Cr, Ni)2 + xN, gamma-phase high N solid solution, or mixed alpha-phase/gamma-CrN can be produced in 304 stainless steel depending on the dose and provided the average temperature during implantation is near or above 400-degrees-C. Nearly complete retention of the implanted dose is observed in 304 SS.
