EFFECT OF N 2 ION IMPLANTATION ON TH E OXIDATION B E H A V I O U R OF FesoNiso ALLOY

چکیده
The high temperature oxidation behavior of Fe50Ni50 alloy foils implanted with i00 keV N2 + ions at a different dose values is studied by using the technique of conversion electron M~ssbauer spectroscopy (CEMS). It has been shown that the implanted foils exhibit considerable adherence of scales and higher oxidation resistance as compared to the virgin foils. This excessive adherence of scales to the surface and higher resistance to oxidation of implanted samples is attributed to nickel enrichment in the surface layers. Various oxides of Fe, Ni and Fe-Ni are identified from the hyperfine interaction parameters of the corresponding CEMS spectra and also from x-ray diffraction measurements.
