A method for the production of a brake disc from a basic body (1), which has a friction ring surface (2). The method includes the steps of the provision of the basic body (1) and the roughening of the friction ring surface (2) by directing an electron beam (5) at the friction ring surface (2). A defined quantity of recesses (3) per mm2 of the friction ring surface (2) is created in the friction ring surface (2). The arrangement of the recesses (3) with respect to one another is predetermined and each recess (3) has a predetermined depth and shape. Then a coating (4) is applied to the friction ring surface without the implementation of an chemical etching step. Furthermore, the invention discloses a corresponding brake disc. |
