Manufacture of Toothed Elements in Nanoausferritic Ductile Iron

The technology currently used for the fabrication of toothed wheels, gear couplings and chain drums involves the induction hardening process or hardening and tempering after carburising.All these processes take a long time and cause adverse changes in the dimensions and surface quality of products, requiring post-treatment 5 Inch machining to remove the resulting cavities.The paper proposes the implementation of gear elements made Bosch Serie 6 KIN85AFE0G Integrated 50/50 Fridge Freezer of ductile iron with nanoausferritic matrix obtained by a new appropriate heat treatment process.The new material offers good performance characteristics and nearly no need for the application of other technological processes commonly used in the manufacture of gears.
