Abstract
In this study, we carried out the characteristics analysis and experiment research of the developed technologies based on surface modifications to enhance the anti-corrosion performance of offshore equipments. The developed technologies are the dipping method to generate super-hydrophilic surface which is then treated to be super-hydrophobic using chemical deposition and lubricant impregnation, and the spray coating method to generate super-hydrophobic surface. It is well-known that the super-hydrophilic and super-hydrophobic surfaces have good anti-corrosion performance. However, the mechanical properties should be maintained. We have verified the anticorrosion performance through the salt spray test and the measuring contact angle. And, we have evaluated the mechanical characteristics such as hardness. As the results, the dipping and the spray coating methods improved the anti-corrosion performance maintaining its mechanical properties at the same coating thickness of about 80 nm.
