Abstract (en)
[origin: WO2013011228A1] According to the method: prior to the end of the treatment, an enclosure (1) is filled with a liquid cooling agent having a high capacity for volume expansion upon vaporisation, said enclosure being arranged to discharge the oxygen contained therein in order to create an inert atmosphere; all of the treated parts are transferred to the enclosure (1); the enclosure (1) is closed; the parts are left in the enclosure for a pre-determined period of time in order to reach a temperature at which the salt freezes and creates a protective barrier; and the parts are removed and subjected to a rinsing operation.
