Resumen
Chromium concentration on steels plays an important role in ion nitriding processes. In this work, the time variation of the concentration of the elements in the near-surface region of the AISI 304 (18% of Cr) stainless steel, during pulsed ion nitriding, was studied. The techniques used were the real time and in situ X-ray diffraction by Synchrotron radiation. Auger spectroscopy, Nuclear Reaction Analysis, and Conversion Electron Mossbauer Spectroscopy. Ion nitriding was performed with a 100 Hz square wave pulsed glow discharge, with different treatment times, in an atmosphere of 80% N and 20% H mixture, under a total 2 2 pressure of 5.6 mbar. The high Cr concentration in the near surface layers (;17 A) and the intermediate ‘S’ phase formation ˚ were explained through the nitrogen ion sputtering during the ion nitriding process.
