Abstract
An oxidation-protected brake disk is made of a fiber-reinforced ceramic material. A method of producing such a brake disk comprises applying at least one paint layer to a brake disk. In order to reduce damage to the brake disk under extreme thermal stress, the brake disk is provided with a layer of a highly temperature-stable paint that is viscous at the operating temperature of the brake disk.
Claims12
A method of producing an oxidation-protected brake disk, comprising coating a brake disk with a high-temperature-stable paint,
- wherein the brake disk is made of a fiber-reinforced ceramic material;
- and
- where said paint is viscous at the operating temperature of the brake disk.
A method of making an oxidation-resistant brake disk, comprising:
- forming a brake disk of fiber-reinforced ceramic material, said brake disk having friction surfaces, contact surfaces, non-friction surfaces, and non-contact surfaces;
- and
- applying a coating to said non-friction and non-contact surfaces,
- wherein said coating comprises a high temperature-stable material which is viscous at high temperature.
