Abstract
A component comprising a component body made of a reaction bonded silicon carbide (RBSiC) is disclosed, the component body having a body surface at least partially coated with a coating, the coating comprising silicon carbide (SiC) with a layer thickness of at least 25 μm. A use of such an SiC coating and a method for manufacturing a component comprising an SiC coating are disclosed.
Claims24
A component having a component body made of a reaction-bonded silicon carbide (RBSiC), wherein the component body has a body surface coated at least partly with a coating, wherein the coating comprises silicon carbide (SiC) having a coat thickness of at least 25 μm.

A method of use of a coating of silicon carbide (SiC) having a coat thickness of at least 25 μm for coating a body surface of a component body, made of a reaction-bonded silicon carbide (RBSiC), of a component, for:
- a) increasing the hardness of the body surface of the component;
- and/or
- b) increasing the strength of the component;
- or
- c) improving the chemical resistance of the body surface of the component;
- or
- d) increasing the temperature stability of the component.
A method for producing a component, comprising:
- producing a component body by fabricating a powder-based green body from silicon carbide (SiC) and a carbon source;
- and performing a reaction firing with infiltration of the green body with silicon (Si) to generate a base body made of reaction-bonded silicon carbide (RBSiC);
- and
- at least partly coating a body surface of the component body with a coating of silicon carbide (SiC) having a coat thickness of at least 25 μm.
