Abstract

A structure for high temperature applications includes a base structure which includes a ceramic composite material, and a coating of a metal-semimetal compound, a metal boride, a metal carbide and/or a metal nitride. Furthermore, a production method and a coating device produces structures which resist high temperature applications with higher process temperatures and difficult chemical conditions.

First claim

What is claimed is:

1. A structure for high temperature application comprising:
a base structure which includes a ceramic composite material; and
a coating material provided on a surface of the base structure, the coating material comprising a metal boride and a metal carbide, and the coating material having a graded structure with a higher amount of the metal boride at an outer surface of the coating material.

2. The structure according to claim 1 , wherein at least one of the following
the base structure has fibers and a matrix; and
the coating has a thickness of 0.1 μm to 200 μm.

3. The structure according to claim 2 , wherein at least one of the following
the fibers are formed from one or several fiber materials, which are selected from a group of fiber materials which comprises C, ceramic materials, SiC, HfC, ZrC, TaC, TiC, ZrB 2 , HfB 2 , TiB 2 , TaB 2 and NbB 2 and nitride materials; and
the matrix is formed from one or several matrix materials which are selected from a group of matrix materials comprising C, ceramic matrix materials, SiC, SiSiC, HfC, ZrC, TaC, TiC, ZrB 2 , HfB 2 , TiB 2 , TaB 2 and NbB 2 and nitride materials.

4. The structure according to claim 2 , wherein
the coating comprises at least one of SiC, HfC, ZrC, TaC, TiC, ZrB 2 , Hffi 2 , TiB 2 , TaB 2 and NbB 2 and nitride materials.

5. The structure according to claim 2 , wherein
the coating is formed from ZrB 2 and SiC.

6. The structure according to claim 2 , wherein
the base structure comprises carbon fibers Cr and an SiC matrix.

7. The structure according to claim 2 , wherein the coating comprises at least one of the following
at least one glassy substance; and
a graded surface; and
a mixture of a metal oxide with boron oxide or semimetal oxide at its surface.

8. The structure according to claim 1 , wherein
the coating comprises at least one of SiC, HfC, ZrC, TaC, TiC, ZrB 2 , HfB 2 , TiB 2 , TaB 2 and NbB 2 and nitride materials.

9. The structure according to claim 1 , wherein
the coating is formed from ZrB 2 and SiC.

10. The structure according to claim 1 , wherein
the base structure comprises carbon fibers Cr and an SiC matrix.

11. The structure according to claim 1 , wherein the coating comprises at least one of the following
at least one glassy substance; and
a mixture of a metal oxide with boron oxide or semimetal oxide at its surface.
