Abstract

Selon le procédé : avant la fin dudit traitement, on remplit en agent réfrigérant, sous forme liquide et ayant une forte capacité d'expansion volumique lors de sa vaporisation, une enceinte (1) agencée pour évacuer l'oxygène contenue dans ladite enceinte, afin de créer une atmosphère inerte, on transfert l'ensemble des pièces traitées dans l'enceinte (1), on ferme l'enceinte (1), - on laisse les pièces dans l'enceinte pendant une durée déterminée pour atteindre une température, selon laquelle le sel se fige et constitue une barrière de protection, on retire les pièces que l'on soumet à une opération de rinçage.
