Functional coatings

Through various coatings, ceramic components and systems can be optimised for their intended use and their functionality extended.

Special coatings on technical ceramics open up completely new application possibilities: Special requirements are realised, for example by applying metallic layers. Bosch Advanced Ceramics is continuously developing this higher functionalisation of ceramics. Ceramic components from Bosch Advanced Ceramics are therefore precisely adapted to their environment and their technical tasks.

Durable coatings to extend functionality

Coatings on technical ceramics can have different objectives: Either the existing properties are improved, for example by applying friction-reducing layers, or entirely new properties are added. For example, ceramics – actually an insulating material – can be made conductive at certain points by applying metallic layers. These layers applied, using the unique Bosch Advanced Ceramics technology, permanently diffuse into the structure of the ceramic base material during sintering. The ceramic can thus be used for completely new applications.

Wide range of coating materials and technologies

Depending on the materials used, the coating can be sintered into the ceramic component at high temperatures (co-firing); alternatively, the coating can be applied to the component following sintering. Then sintering must be carried out again at lower temperatures (post-firing). Co-firing achieves better layer adhesion, but cannot be used with all materials. Bosch Advanced Ceramics has already realised many coatings, for example with gold, silver, platinum, chrome but also hard materials such as DLC. The wide range of coating technologies ensures an extensive choice of materials here.
