Design, Synthesis, and Characterization of Functional Glass-Ceramic Coatings for Anti-Fouling Surface Applications

Co-Supervisor: Nurullah Çöpoğlu

Fouling Description

The fouling issue has kept on since the first vessel travel. Especially, while a vessel docks, the biofilm that is the indicator for fouling starts to occur. This occurring process improves with some factors such as rising temperatures, rising light ratio, etc. This biofilm occurring develops with two stage as micro fouling and macro fouling. The stage of macro-fouling proves the most ratio of lost efficiency as approximately 77%. Also, developing technologies have given new areas for underwater applications such as Infrastructure pipes, port steels. As can be predicted, fouling is problem for these underwater structures. In addition to organism fouling, the accumulation of calcium carbonate some surfaces like an inner teapot or external surface of heat exchanger is also called fouling. On the other hand, decreasing water sources is the most important topic for human life. As can be predicted, the giant water storage structures will appear in near future. Therefore, fouling description will be in these structures.

Inorganic Glass-Ceramic Coating Approach for Anti-Fouling

The anti-fouling can be explained as mechanisms that counteract the types of contamination mentioned above. These attempts have been processed with organic structures since the starting. However, as it is known, the organic structures disappear with time, thus the maintenance expenses are the issue for industries, especially marine industry, and marine environment.  So, this work aims to set up the inorganic coating structure for the resistance of fouling with more long using life and more environment-friendly thanks to its unique properties such as perfect corrosion resistance, superior wear resistance, high mechanical strength, etc.
