Method for manufacturing brake disk for disk brake of motor vehicle i.e. passenger car, involves forming two regions of brake disk with different material compositions such that regions have different coefficient of thermal expansions

摘要

The method involves producing a brake pot (16) and a friction ring (18) integrally by spray-forming, and forming two regions of a brake disk (14) with different material compositions such that the regions have different coefficient of thermal expansions. A transition area (24) of the brake disk is formed such that the friction ring passes into the brake pot in an axial direction (28) of the brake disk, where the brake pot and the transition area of the brake disk are formed of nickel and/or cobalt and/or manganese.
