Abstract

The characterization of passive films formed on 316L stainless steel surface implanted in a femur for 1 year is discussed according to Mössbauer Spectroscopy and scanning electron microscopy (SEM).The Mössbauer spectroscopy shown that surface layer consist mainly of oxidic species and suggested a possible apparition of a ferrite phase on surface In according to Mössbauer Spectroscopy, SEM shown that during implantation a change in the superficial microstructure took place and a corrosion process was presently..

Keywords
