Morphology, Structure and Corrosion Resistance of Nano-Enamel Coating Changed on Ti-6Al-4V Alloy

Using a sol-gel method and impregnation technology to produce nanoenamel coating on polished Ti-6Al-4V alloy. The morphology, structure and phase composition of nanoenamel coatings modified on mild steel were identified with X-ray diffraction (XRD), scanning electro microscopy (SEM) and tested by some electrochemical methods, such as open circuit potential and potentiodynamic polarization testing [1]. All of these method can select the samples which perform the best corrosion resisitance.
