VACUUM HARDENING


VACUUM HARDENING

Our most recent investment to date is the introduction of vacuum hardening, this process provides for a completely clean component after treatment with minimum levels of distortion and movement.

The control of the process uses the latest PC technology, controlling furnace temperature with two thermocouples and the actual temperature of the work being treated using up to four thermocouples.

NITRIDING TREATMENTS


NITRIDING TREATMENTS

Gaseous nitriding/nitrocarburising can be performed on a wide range of component sizes to provide a very hard surface coat.

When ammonia is heated to nitriding temperature of around 500 degrees centigrade it dissociates into its components of hydrogen and nitrogen if a catalyst is present. In nitriding steel is the catalyst.

In simple terms the result is a nitrogen rich layer at the surface of steel which can be, dependant on the material treated, up to 1000 Hv.
