Surface conversion coating is important for a wide range of industrial applications to prevent corrosion and enhance the adhesion of functional and decorative paints to metal parts. In conventional coatings, components such as Cr(VI) or P could lead to health and environmental issues, thus there is a great need to develop new technology. It is also crucial to further understand the coating formation and corrosion prevention mechanisms in the novel systems where new additives are introduced to enhance the coatings’ anticorrosion and adhesion properties. In this work, we studied the effects of additives’ concentration and oxidation states on the formation of Zr-based coatings containing hybrid organic-inorganic additives. A multi-modal approach combining electron microscopy and synchrotron X-ray absorption spectroscopy was utilized to characterize the morphology and chemistry of the coatings. This work advanced our knowledge concerning organic-inorganic additives in the surface conversion coating for the development of future greener coating technology.
