摘要

An arrangement for radiation hardening, comprises a radiation chamber (2) with an inlet and an outlet for the component which is to have a coating hardened, and a radiation area, e.g. an electron beam or ultra violet light area. The inlet region (3) and/or the outlet region (4) is in the form of an inert gas lock (15,16), and has an outer mantle tube and an inner mantle, with a gap between them. The annular gap has an inert gas supply connection. The inert gas is e.g. carbon dioxide, a noble gas, nitrogen, or a gas containing one of these gases.
