摘要：

Oxide scales on the INCONEL alloy 617 were investigated by means of glow discharge optical emission spectrometry (GDOS). Various glow discharge modes were applied to find optimum conditions for the transformation of intensity-time profiles into concentration-depth dependencies using the alloy matrix as a reference. The calibration of the depth axis was provided by geometry determination of the sputtering craters. Element concentrations were calculated from intensity ratios, corrected with respect to sputtering rates and discharge current ratio. Corrections with regard to the light emission are not necessary, because, for the investigated elements the latter is independent of the chemical bonding and the matrix, within experimental error.
