  • Method for producing a friction brake body
    Patent number: 12485504
    Abstract: A method is disclosed for producing a friction brake body, in particular a brake disc, which has a main part with a frictional contact region. A wear protection layer is produced on the frictional contact region by way of laser cladding using a laser beam oriented towards the frictional contact region. The wear protection layer is produced by at least one pulverulent additive during the laser cladding. At least two pulverulent additives are added simultaneously such that the dwell time thereof in the laser beam differs.

  • Friction brake body, friction brake, and method for producing a friction brake body
    Patent number: 12398771
    Abstract: A friction brake body, in particular a brake disc, for a friction brake of a motor vehicle is disclosed. The friction brake body has a main part with at least one wear protection layer on at least one frictional contact region of the main part. The wear protection layer forms a frictional contact surface on the wear protection layer face facing away from the main part. The degree of hardness of the wear protection layer increases incrementally or continuously from the main part to the frictional contact surface.
