Ceramic coatings are always used when other materials reach their material limits. For example, the conditions and requirements at the interfaces of metallic constructions are often different from those in the volume of the material itself. These can be, for example, thermal stress, excessive wear, electrical conductivity or contact with melts. In these cases, a ceramic coating can achieve improved and/or additional functionalization of the surface, extend the service life of components and save costs. The application of ceramic layers thus results in a functional separation of the surface and the actual material, with the aim of optimally adapting the surface properties of the component to the environmental influences.

What properties do ceramic layers offer?

The possible properties of ceramic layers are as diverse as the material-specific properties of ceramic materials themselves:

  • wear resistance
  • high hardness
  • Heat and cold resistance
  • corrosion resistance
  • electrical insulation
  • low thermal conductivity
  • high thermal insulation
  • Resistance to acidic and basic environment
  • Resistance to organic solvents
  • piezoelectric properties
  • Biocompatible

No ceramic material can cover all of the above properties at the same time. However, the final property of the ceramic coating is largely dependent on the raw materials used. The choice of raw materials must therefore be carefully tailored to the respective application.
