Abstract
A method and a system for cooling treating metal parts exiting a nitriding/nitrocarburizing treatment in molten salt baths, comprising a cooling chamber in direct relation with a nitriding/nitrocarburizing station for receiving parts therefrom; a gaseous nitrogen feeding unit connected to the cooling chamber and configured to create an inert atmosphere within the cooling chamber; and a screened transfer path between the nitriding/nitrocarburizing station and the cooling chamber; wherein after exiting molten salt baths of the nitriding/nitrocarburizing station, the treated parts are transferred to the cooling chamber through the screened transfer path, and cooled therein to a minimum temperature above a temperature at which salts congeal.
