The limiting oxygen concentration, (LOC), also known as the minimum oxygen concentration, (MOC), is defined as the limiting concentration of oxygen below which combustion is not possible, independent of the concentration of fuel. It is expressed in units of volume percent of oxygen. The LOC varies with pressure and temperature. It is also dependent on the type of inert (non-flammable) gas.
Enclosed Additive Manufacturing System
A method of additive manufacture is disclosed. The method may include restricting, by an enclosure, an exchange of gaseous matter between an interior of the enclosure and an exterior of the enclosure. The method may further include running multiple machines within the enclosure. Each of the machines may execute its own process of additive manufacture. While the machines are running, a gas management system may maintain gaseous oxygen within the enclosure at or below a limiting oxygen concentration for the interior.

Method for oxidizing metal powder
PendingCN122161681AAdditive manufacturing apparatusTransportation and packagingPhysical chemistryEngineering
Provided is a method for oxidizing metal powder that easily controls oxidation of the metal powder. A method for oxidizing metal powder (M) housed in a container (3), wherein: the container (3) is placed in an atmosphere of an inactive gas at a first pressure higher than atmospheric pressure; and a mixed gas containing an inactive gas and oxygen is introduced into the container (3) in such a manner that the oxygen concentration in the container (3) is lower than the limit oxygen concentration of the metal powder (M), and the pressure in the container (3) is raised to a second pressure higher than the first pressure.
