摘要

#CMT# #/CMT# The brake disc comprises a brake disc base body (1) having a friction ring surface (2), which is coated with a thermal spray coating, where a recess line extends itself over the friction ring surface that has a undercut at both vertical walls with respect to its base and a undercut recess line provides a holding primer for the thermal spray coating. Spiral- or concentric circular-shaped undercut recess lines passes through the total friction ring surface, where an omega-shaped cross-sectional profile of the recess line is formed. #CMT# : #/CMT# An independent claim is included for a method for producing brake disc. #CMT#USE : #/CMT# Used as a brake disc. #CMT#ADVANTAGE : #/CMT# The brake disc can be economically manufactured with improved corrosion protection and wear properties, and with less consumption of space. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a schematic cross-sectional view of a brake disc. 1 : Brake disc base body 2 : Friction ring surface 2' : Surface.
