Definitions
- the surface layer in the engagement area of the gearwheel is compacted by means of a pusher tool in the form of at least one gearwheel, which has either an external toothing (EP 0 552 B1) engaging in the toothing of the powder metal blank or an internal toothing (AT 406 836 B), with the aid of which the sliding speed can be reduced between the tooth flanks of the powder metal blank and the press tool.
