Brake disc protected from oxidation

摘要

Brake disk protected from oxidation is made of fiber-reinforced ceramic material. One layer made of a high temperature-resistant lacquer (9) is in a semifluid state at the operating temperature of the brake disk. Independent claims are also included for the use of a high temperature-resistant lacquer for a brake disk, and for a process for producing the above brake disk. Preferred Features: The glass transition temperature of the lacquer lies above about 400 degrees C and the lacquer is temperature resistant up to about 1200 degrees C. The lacquer is based on a magnesium/borosilicate compound. The lacquer additionally contains color pigments which change color above a specific temperature. The friction surfaces (4) and the contact surfaces (10,11) of the brake disk are not covered by the lacquer.
