METHOD FOR REMOVING OXYGEN FROM INERT GAS USED FOR HEAT TREATMENT PROCESS OF TITANIUM POWDER MOLDED OBJECT

摘要

The present invention relates to a method for removing oxygen from inert gas used for a heat treatment process of a titanium powder molded object, which introduces, to a heat treatment process of a titanium powder molded object, high-purity inert gas from which a very small amount of oxygen of several ppm to several tens of ppm contained in an extremely high-purity inert gas of 99.9 to 99.999% is removed, thereby preventing a phenomenon that mechanical properties of the titanium powder molded object are degraded by oxidation of the titanium powder molded object during the heat treatment process.;COPYRIGHT KIPO 2018
