The Ion Microprobe Mass Analyser (IMMA) has been widely used for surface and high sensitivity analysis of various materials. For quantitative analysis of homogeneous materials, the calibration curve method is effective using reference samples [1][2]. On the other hand, quantitative methods for surface oxide layers have not been established, because the existence of oxygen significantly enhances secondary ion intensities [1]. In addition available reference samples can not be obtained.

It has been reported that several elements segregate on the surface of cold-rolled steel sheets during annealing in a hydrogen reducing atmosphere [1,2]. In the present report, two-dimensional distributions, depth-profiles and the chemical state of the segregation were investigated by IMMA (ARL), ESCA (V.G.) and XRF.
