The determination of binary mixtures in metallic coatings
Some common metallic coatings on steel are in fact binary mixtures (Gignoux and Gouel, 1991). These are Zn/Al, Zn/Ni and Zn/Fe. The measurement of the first two coatings using x-ray fluorescence easily yields value for both the coating weight and the composition. However, Zn/Fe (galvanneal) poses sp...

Summary: | Some common metallic coatings on steel are in fact binary mixtures (Gignoux and Gouel, 1991). These are Zn/Al, Zn/Ni and Zn/Fe.
The measurement of the first two coatings using x-ray fluorescence easily yields value for both the coating weight and the composition.
However, Zn/Fe (galvanneal) poses special problems because Fe K
α fluorescence arises from the Fe contained in the coating and from the steel substrate.
A solution involving a special x-ray beam geometry and correct selection of beam energy is presented. |
