DETERMINATION OF SURFACE COMPOUND FORMATION BY BACKSCATTER MÖSSBAUER SPECTROSCOPY

Abstract
The detection and identification of a surface compound formation on a steel surface was made using a backscatter Mössbauer effect technique. The compound was identified as β-FeOOH from Mössbauer effect parameters of iron oxide and oxy-hydroxide compounds. An estimate of the compound thickness is given based on a calculation of the backscatter amplitude versus distance into the sample. This technique can be used to identify corrosion products on the surface of iron bearing materials.
