Abstract
We have investigated the oxidation of stainless steel alloy 440C at va rious temperatures using Rutherford Backscattering Spectrometry (RBS), Auger Electron Spectroscopy (AES), Energy Dispersive X-ray Analysis ( EDX) and Electron Spectroscopy for Chemical Analysis (ESCA). The chemi cal state of the various oxides formed at each temperature was measure d by ESCA. The relative surface concentrations of Cr and Fe were measu red using all four techniques. EDX data provided us with a standard fo r bulk concentrations of Cr and Fe. The results of RBS and AES were us ed to develop an empirical relationship between the Cr/Fe ratio and th e heat treatment temperature. This empirical relationship can be used to determine the temperature at which a given component made of stainl ess steel alloy 440C, has been operating by measuring the Cr/Fe ratio at the surface.
