\n\tThe success of plasma and gas nitriding at low temperatures (lower than 840\u00b0F) and solution nitriding at high temperatures is associated with the absence of chromium nitride or carbide precipitation, and thus with the formation in the surface layer of a particular phase called the S-phase. This nitrogen- and\/or carbon-rich phase presents higher concentration of the interstitials when treated at lower treatment temperatures and when high-chromium alloys are used, resulting in better properties. <\/p>\n
\n\tThe figure shows the XRD patterns of untreated and plasma-nitrided AISI 316 stainless steel at 790\u00b0F. It illustrates the displacement of the peaks corresponding to the ?-phase to the left, with increasing nitrogen, as well as the broadening of these peaks, compared to the ?-phase peaks of the untreated steel.<\/p>\n
