Numerous approaches are in practice to mitigate corrosion. Among all of these approaches, conversion coatings play an effective/promising role in corrosion protection. However, studies have begun to find an alternative to conversion coatings due to environmental problems and carcinogens since the 1970s. One of the most important alternatives to these coatings is the silane-based sol-gel coating containing a corrosion inhibitor which in addition to environmental problems, has improved corrosion protection properties compared to conventional conversion coatings. In addition, the sol gel method is an environmentally friendly method that has been shown to improve the protective performance of sol gel coatings in various fields such as metal, such as steel, aluminum, copper, magnesium and alloys. In this method, impurities do not enter and at the end of the process, the product does not need to rinse. The sol gel process temperature is generally low (often close to room temperature), so thermal evaporation and degradation of receptor species, such as inorganic inhibitors, are minimized. Because liquid precursors are used in this method, it is possible to produce complex coatings as well as to produce thin films without the need for machining or melting.
