A brief review of environmentally benign antifouling and foul-release coatings for marine applications 总被引:1,自引:0,他引:1

Antifouling coatings for ship hulls are a very important topic in coating research. They are essential with respect to fuel consumption of ships: without antifouling coating, biological species start to adhere to the ship’s exterior, leading to a gradual increase in fuel consumption. To date, the working principle of most of the paint systems applied is based on slow release of toxins in time (self-polishing coatings). In this article, we discuss the environmental impact of marine antifouling coatings based on quantitative data available from literature. In addition, we critically review hydrophilic antifouling and hydrophobic foul-release coatings as toxin-free alternatives and discuss their potential for replacing self-polishing coatings. 相似文献

Evaluation of the corrosion resistance of phosphate coatings obtained by anodic electrochemical treatment 总被引:1,自引:0,他引:1

The corrosion resistance of phosphate coating obtained by anodic electrochemical treatment at 4–6 mA/cm2 is addressed in this paper. The corrosion performance of these coatings is also compared with the coatings obtained by chemical treatment. The regenerated phosphoric acid under the influence of anodic current causes a large variation in morphological features of the coatings. Immersion and salt spray tests indicate the ability of these coatings to act as a barrier film on mild steel. Polarization and electrochemical impedance spectroscopic (EIS) studies indicate that the corrosion resistance of phosphate coatings obtained by anodic treatment decreases with increase in current density employed for deposition. In spite of their higher coating weight, the corrosion resistance of phosphate coatings obtained by anodic treatment is inferior to those obtained by chemical treatment. The porosity or discontinuities created due to the dissolution of the coating under the influence of anodic current are considered responsible for the inferior corrosion resistance of these coatings. The study concludes that anodic treatment has only a limited scope for preparing phosphate coatings with improved corrosion resistance. 相似文献
