CEMENTATION OR CARBON CEMENTATION TREATMENT

Semi-finished products are heated in chamber furnaces until reaching temperatures between 880° and 920° C, and air enriched with methane is blown inside the furnace so that carbon can be absorbed on the surfaces of the various components.
The following oil hardening process at 850° C confers a high level of hardness and resistance to wear to the external carbon layer.
In conclusion, stress relieving is carried out at temperatures between 180° and 240° to obtain the requested final hardness and a variable depth of the cemented layer according to the time span of the blowing phase.

CARBONITRIDING TREATMENT

Ammonia is added in some cases, to obtain harder nitrides.
In conclusion, our partners developed a series of treatment cycles, tested on a regular basis, that allow reaching hardnesses and cementation depths as requested by our customers.
