In the Laboratory of Heat and Chemical-Chemical Treatment (P6), heat treatment processes of nickel and titanium superalloys, tool and bearing steels at temperatures up to 1350oC are carried out, as well as carburizing and nitriding processes for low-alloy steels with the use of acetylene and ammonia. Hardening processes are carried out using a modern high pressure gas method with the use of N2 and Ar medium.
The basic equipment of the heat and thermo-chemical treatment laboratory is:
Vacuum Heat Treatment Mono Therm HK.446.N.20.gr – A single-chamber vacuum furnace used in the heat treatment of nickel superalloys. The furnace is equipped with a heating system with a total power of 80kW. The batch chamber with a capacity of 3 m3 and a working space of 600x400x400mm is equipped with a set of 9 sheathed thermocouples with the possibility of temperature measurement with an accuracy of 3oC. The heating process can be carried out by convection up to 950oC (in an argon or helium atmosphere) or by radiation up to 1350oC (in a vacuum).
The furnace is equipped with a vacuum system consisting of a rotary pump and a diffusion pump, thanks to which the process can take place in a vacuum up to 5 × 10-5 bar.
The furnace is equipped with a system for high-pressure gas quenching in an argon or helium atmosphere at a pressure of up to 10 bar.
Vacuum Heat Treatment Mono Therm furnace HK.446.VC.10.gr – A single-chamber vacuum furnace for carburizing, nitriding and carbonitriding with acetylene and ammonia in a nitrogen atmosphere or in a vacuum. The furnace is equipped with a heating system with a total power of 80kW. The batch chamber with a capacity of 3 m3 and a working space of 600x400x400 mm is equipped with a set of 9 sheathed thermocouples with the possibility of temperature measurement with an accuracy of 2oC. The heating process can be carried out by convection up to 950oC (under nitrogen atmosphere) or by radiation up to 1150oC (under vacuum).
The furnace is equipped with a vacuum system consisting of a rotary pump and a Roots pump, thanks to which the process can take place in a vacuum of up to 9 × 10-3 bar.
The furnace is equipped with a system for high-pressure gas quenching in a nitrogen atmosphere at a pressure of up to 10 bar.
The HK.446.VC.10.gr furnace is certified in accordance with the AMS 2750 standard for the production and processing of components used in the aviation industry.
