Abstract: A ferritically nitrocarburized rotational member of a vehicle brake is disclosed, including a rotational member having a friction surface configured for braking engagement with a corresponding friction material. A compound zone is disposed at the friction surface. An exposed surface of the compound zone is exposed to an atmosphere. The area of the exposed surface includes from about 0 percent to about 14 percent graphite.
