Abstract

The Zn-Mg coatings are considered as the next generation of steel covering that should be used in automotive industry since they improve the corrosion resistance of the base material. The weakness of this coating lies in its higher hardness and lesser ability of plastic deformation in comparison to the purely zinc coatings. The Zn-Mg coatings break out and by higher deformation even flake off. This can influence the corrosion properties of the material. The experiment described in this article analyses the properties of the Zn-Mg coating in the dependence on the extent of deformation by different temperatures. The specimens were gradually deformed until their total rupture. Subsequently, the coating of deformed specimens was analysed by using electron microscope and the x-ray diffraction method. X-ray diffraction method is used for the evaluation of qualitative changes in the real structure of polycrystalline material. This method helps to find a suitable technology that do not cause cracking of the Zn-Mg coating.
