Research progress of sol-gel ceramic coating: A review

The sol–gel method is a simple and low-cost technique that requires low temperature for the reaction process. Sol-gels can be made from a wide variety of ceramic materials, including alumina, chromium, silica, and zirconium. This technique has been used in a variety of applications, including corrosion prevention, biomedical applications, and electronic devices. The sol–gel technique has made significant progress in a variety of fabrication applications. Numerous papers have reported on the incorporation of ceramic materials with other materials to increase the performance of sol–gel coating. The ceramic sol–gel coating increased the corrosion resistance and thermal properties of the coated materials while remaining a low-cost approach. This paper highlights current reports on the various applications of sol–gel ceramic coatings.
