摘要:
The invention relates to the use of a composition comprising a nanoscale powder, a porous ceramic powder, and a solvent to protect a metallic surface against chemical attacks at high temperatures, in particular in reducing and/or carburizing atmosphere, and to a corresponding method. The invention further relates to a system part that comprises a metallic surface that is exposed to a reducing and/or carburizing atmosphere in the operating state, wherein the surface is coated with a porous protective coating that has a specific surface area of at least 20 m
