1. A brake assembly comprising:
a rotor having a surface configured to interface with another component of the brake assembly, wherein the rotor comprises:
a carbon composite substrate, and
a high temperature coating comprising a bond layer of a metal carbide on a surface of the carbon composite substrate; and
an insert joined to the surface of the rotor without a mechanical fastener, wherein:
the insert defines a tough mechanical contact surface configured to protect the rotor, and
the insert comprises a monolithic ceramic substrate which includes a rare-earth silicate or rare-earth disilicate.
