Sol-Gel-Technique
The coatings are based on the principle of the sol-gel-technique. A cost-efficient dip- or spray-coating process is carried out via a solution of organic solvents and organometallic compounds. During subsequent drying, a polymer-like layer is formed on the material. This layer is converted by thermal treatment into a ceramic layer. The functional modification is obtained by the coating material itself or the homogeneous incorporation of active fillers into the coating solution.
