The structure, surface morphologies, and phase compositions of the phosphate coating on the carbon steel substrate was investigated by SEM, XRD. It is shown that the phosphate coating became more dense with fewer microholes and an increasing concentration of ozone in phosphate bath in the range of 0.0 to 1.62 mg/L. The coating compositions were Zn3(PO4)2 · 4H2O (hopeite) and Zn2Fe(PO4)2 · 4H2O. Potentiodynamic polarization and immersion tests were used to evaluate the corrosion properties of the treated samples. The coating showed good corrosion resistance properties.
