Quantitative Analysis of Ultra-Fine Goethite in Rust Layer on Steel Using Mössbauer and X-ray Diffraction Spectroscopy

Abstract

We have proposed determination procedure of the relative amounts of rust constituents of steel. Mössbauer spectroscopy provides the relative amounts of crystalline rust constituents including ultra-fine crystals. A quantitative analysis of ultra-fine crystals is possible with the resolution of several percent by comparing the Mössbauer results with the relative amounts of rust constituents determined by X-ray diffraction spectroscopy.
