Vacuum Heat Treatments
The heat treatments are sequences of heating, maintenance and cooling stages, performed at predetermined temperatures, with a predetermined and defined thermal gradient.
These processes are used to modify the microstructure of materials such as metals and alloys, to which they confer properties capable of improving their performance.
The use of vacuum technology with a pressurized inert gas cooling, combined with the control and management of the heat treatment parameters, allows to respond to the ever increasing demands in terms of quality of the heat treated materials.
- Overall management of the thermal cycle parameters through a PLC.
- Possibility to use different cooling rates, based on the base materials types, the geometry of the parts and the required mechanical properties, by regulating the cooling pressure and time.
- Absence of oxidation and decarburization because the heat treatment is performed in high vacuum atmosphere (p < 10-5 mbar) and cooling is performed with inert gases (Argon / Nitrogen).
- Improved internal structures.
- Absence of overheating.
- Reduction of distortions.
- Absolute respect for the environment in ecological terms.
- Components of engines
- Components of actuation systems
