Method for manufacturing friction element such as synchronizer ring and flap disk for vehicle clutch, involves etching friction surface of friction element, where etching takes place by galvanic etching process

摘要

The method involves etching the friction surface of the friction element (1), where the etching takes place by a galvanic etching process. The etching takes place as photochemical etching. The structures of different depth are etched. The friction element is manufactured exclusively by a non-cutting process.
