A technique for identification of phases on galvannealed coatings on extra low carbon and
interstitial free steel sheets is presented using a combination of electrochemical stripping
method and a grazing incidence angle X-rays diffraction.
The different Zn-Fe phases show
characteristic corrosion potentials, which can be observed as plateaus in the galvanostatic
It was found that the extension of these plateaus are directly related to current
density, and so the value of 2 mA/cnr was the best one for this system.
The small depth of
the incident beam to grazing-incidence X-Ray diffraction have allowed the identification...
