Abstract
Mixed metal oxide ceramer coatings were developed using linseed oil as the organic phase with titanium i-propoxide, and zirconium n-propoxide as the inorganic sol-gel precursors. The overall goal of this study was to develop a primer that will provide corrosion protection and better adhesion to metal substrates with minimal environmental impact. Zinc acetate dihydrate was introduced to the system as an anticorrosive agent. Various coatings properties such as adhesion, hardness, impact resistance, flexibility, and tensile properties were investigated as a function of sol-gel precursor type and content. In addition, electrochemical impedance spectroscopy (EIS) was used to evaluate the corrosion properties of these mixed metal oxide inorganic/organic coatings.
