ABSTRACT

A method for producing a brake disc that includes a metal base body with a hub
fastening and a metal friction ring is described. The hub fastening provides
an annular bub contact surface, and the friction ring has two opposing annular
friction surfaces arranged around the rotational axis of the base body. The
base body is cast from metal, after which material may be removed from the
friction surfaces and/or the hub contact surface so that the friction surfaces
exhibit a defined radial gradient relative to the hub contact surface. A
wear-protection layer is then applied to one or both friction surfaces.
Thermal stresses generated during this coating process deform the friction
surfaces such that the magnitude of the initial radial gradient is reduced,
resulting in a smaller residual gradient.
