Heat Treatments for Aerospace Applications

Within the aerospace industry many components are manufactured from titanium, aluminium and exotic alloys for a combination of strength, lightweight and heat resistance. Such materials are also highly reactive to oxygen and nitrogen i.e., air, during the manufacturing process and hence need to be processed in an inert atmosphere of argon. For example, the turbine blades used in aero jet engines are cast under an atmosphere of argon and the undergo various heat and deposition processes also under an argon purge.

Depending on the type of heat treatment either a NitroØ or ArgonØ system can be used to effectively recycle the argon purge gas used during the heat treatment. For extremely contaminated argon purge streams a combined ArgonØ /NitroØ can be deployed.

In addition to reducing the processing cost associated with argon purge the GR2L recycle solutions also dramatically reduce the scope 3 CO2 footprint associated with the extraction of argon from atmospheric air and assist the aerospace industry in implementing its net carbon zero strategy.
