Conversion electron Mössbauer spectroscopy (CEMS) and XPS has been used for the surface analysis of an X10CrNiTi 18/9 (DIN 1.7440)-type stainless steel in order to determine the supposed structural and/or chemical changes in the surface layer caused by polishing. Both, CEMS and XPS results can be associated with the appearance of Fe nitride in the outer layer of steel samples after polishing, while no sign of nitrogen was detected in the bulk material.
