Abstract

In the production of Zn hot dip galvanized steel sheets, the concentration of Al in the galvanizing bath must be maintained within a limited range to ensure optimum performance. For this purpose, an accurate determination of Al by X-ray fluorescence spectrometry was studied.
The results were as follows:
(1)The AlKα line intensity increased with the lapse of time after sample preparation because of the enrichment of Al in the near surface of the samples.
(2)An accurate analysis was performed by peparing a sample with an SiC abrasive paper of coarse grit size 40 and starting the X-ray intensity measurement at a short time elapsed of 3 min after sample preparation.
