Abstract
A ceramic heat insulation layer applied to a metal structural part or to an intermediate adherent layer thereon, has the surfaces of its inner, open pore structure coated with a passivating ceramic material or a metal deposition material for improving the properties of the heat insulation layer.
Claims10
A process for producing a heat insulation, ceramic layer on a metal structural part, comprising:
- depositing a material containing zirconium oxide onto a metal structural part to form a heat insulation layer on said metal part, said heat insulation layer having an open, inner structure, and
- impregnating said heat insulation layer with a liquid containing a passivating agent of ceramic nanocrystalline particles to form a passivating coating of said ceramic particle on surfaces of said open, inner structure of said heat insulation layer, and
- wherein said ceramic particles of said passivating coating infiltrate and are confined in said inner structure of said heat insulation layer.
A process for producing a heat insulation, ceramic layer on a metal structural part, comprising:
- depositing a material containing zirconium oxide onto a metal structural part to form a heat insulation layer on said metal part, said heat insulation layer having an open, inner structure
- impregnating said heat insulation layer with a liquid containing a passivating agent of platinum to form a passivating platinum coating on surfaces of said open, inner structure of said heat insulation layer, and
- heat treating said insulation layer and the metal structural part.
