SiC/SiC component as curved tile with EBC coating.

Fiber-reinforced ceramics (ceramic matrix composites, CMC) offer a versatile material basis for saving energy and resources. Whether in applications for temperature-stressed components or at particularly high damage tolerance, abrasion resistance and resistance in corrosive media – CMCs are increasingly being used in vehicle construction as well as energy and heat technology. For the use under extreme thermal loads, corrosion-resistant coatings (environmental barrier coatings, EBC) are applied to the fiber-reinforced ceramics. The EBCs are adapted to the ambient conditions and offer reliable protection against oxidation and hot gas corrosion.
