US 6,306,457 B1 · Coated system and method for its manufacture and its use

Abstract

A coating system and a method for its manufacture are provided. An electrically conductive base coat and a porous overcoat lying over the base coat are arranged on a ceramic substrate. At least one additional deposited layer is arranged on the base coat in such a way that the additional layer is formed in the pores of the porous overcoat adjacent to the base coat. The additional layer is deposited either by currentless or electrolytic deposition. For electrolytic deposition of the additional layer, the ceramic substrate sintered with the base coat and the overcoat is submerged in an electrolytic bath and the base coat is connected as a cathode. The currentless deposition takes place from a solution of the metal to be deposited with the addition of a reducing agent.

Dependent claims

A method for manufacturing a coated system, comprising:

providing a ceramic substrate;
applying an electrically conductive base coat to the ceramic substrate;
applying a porous overcoat to the base coat;
and
depositing at least one additional layer through pores of the overcoat onto the base coat;
wherein
the at least one additional layer deposits in a plurality of pores of the porous overcoat, the plurality of pores being adjacent to the electrically conductive base coat, and
the at least one additional layer has a defined thickness, the defined thickness being less than a thickness of the porous overcoat.
