NitridingSpecified wherever freedom from distortion is of paramount importance to a wear resistant or fatigue prone component, nitriding has become an established process within many fields of engineering. Recognising the need for improved process control to offset the disadvantage of lengthy processing times, Bodycote Thermal Processing pioneered the use of infra-red analysis and computerisation to monitor and control the ammonia dissociation. This, coupled with a wide range of regularly operated cycles, enables Bodycote to provide a systematic turn-round of customers work, irrespective of the case depth required.
EXTENDED RANGE
Improvements resulting from developments in plasma control technology now enable a wider range of process temperatures and times to be utilised. Hence, in addition to the generally nitrided steels, an extended variety of materials can benefit from the plasma nitriding facility including all types of stainless steel, maraging steels, hot work and cold work tool steels, high speed steels, cast irons and titanium alloys.
OPTIMUM MECHANICAL PROPERTIES
The employment of lower nitriding temperatures down to 400 degrees C further reduces the risk of distortion, and enables higher core strength to be retained together with the option of higher surface hardness.
MINIMUM COST
Plasma nitriding provides engineers with a most cost effective means of combining optimum mechanical properties and component stability for those applications which demand high strength with high wear resistance.
Heating is confined only to the surface of the component being treated, and this coupled with the vacuum environment, guarantees thermochemical control throughout the process and greatly reduced unit costs.
