Method for producing a porous layer

摘要

The method involves coating a dispersion, which contains a metal agent and a ceramic agent, on a substrate (1). A part of the metal agent is contained in the form of metal particles and a part of the ceramic agent is contained in the form of ceramic particles in the dispersion. The dispersion is transferred into a cermet coating at a temperature above 250 degree celsius. The ceramic agent is a metal (9), which forms the ceramic material as oxide.
