Abstract

The invention relates to a method for testing the stress state of a brake disc comprising a hub part (10) and a friction ring (11u). The friction ring (11u) is coated by laser cladding and subjected to a process step in which the coated friction ring is at least partially destroyed. According to the invention, it is proposed that a distortion of the coated friction ring be measured before the partial destruction and that the friction ring is then partially destroyed. A distortion (a2) of the partially destroyed friction ring (11c) is measured and compared with the distortion of the coated, non-partially destroyed friction ring.
