Ancient phosphorus-containing iron-based alloys are often reported to be strongly resistant toward corrosion, but the mechanisms of this protection have not yet been explained. In order to better understand the role of this element, in the conditions of atmospheric corrosion, Judith Monnier and co-workers in France used micro-XANES spectra to highlight phosphorus distribution and speciation in two ancient iron-based samples.
