Abstract
The Zn-Mg coatings are considered as the next generation of steel covering to be used in automotive industry since they improve the corrosion resistance of the base material. The article is focused on the X-ray diffraction analysis of Zn-Mg coating in dependence on strain. The specimens made from a material, which has Zn-Mg coating, were gradually deformed until they became totally fractured. Subsequently, the specimens´ surface layer was analysed using X-ray diffraction. X-ray diffraction methods are used for evaluation of the qualitative changes in the real structure of the polycrystalline material. The modification of the real structure is considered as a degree of plastic deformation, change of crystallite size and their orientation depending on deformation.
