Claims19
A brake disk with a surface which is structured in order to increase adhesion of a coating on the surface, wherein a structuring of the surface comprises at least one groove-shaped recess having a trapezoidal cross-section, a width of which decreases as a depth of the recess increases, wherein the groove-shaped recess has a first recess wall, a second recess wall and a groove base, wherein the grooved-shaped recess has a width measured approximately in parallel to the surface from the first recess wall to the second recess wall and a depth measured approximately orthogonally to the surface from the surface to the groove base, wherein the width decreases from the surface towards the groove base, wherein a second angle measured from the groove base to the second recess wall is greater than 90°, wherein a first angle measured from the groove base to the first recess wall is less than 90°, and wherein the at least one recess has a shape of a spiral structure.
