Abstract In order to investigate transport phenomena during oxide scale growth commonly a two-stage oxidation technique (16O2/18O2) is used [1–4]. In this contribution, SNMS measurements have been performed on an industrial high temperature alloy after oxidation of the material. The problem of depth calibration in this particular case is examined. It is shown that the variation of the particle density in the scale and in the substrate can be neglected and that only the variation of the sputter yield has to be taken into account. In order to validate this approach two independent techniques have been applied. First, a taper section of the sample has been prepared and a SNMS line scan has been measured. Secondly, thermogravimetric measurements have been performed to determine the scale thickness after each oxidation step.
