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.
