Abstract
Systems and methods for hydrogen out gas of a porous metal scaffold are disclosed. A method can comprise heating a porous metal scaffold for a period of time sufficient to remove at least a portion of a hydrogen concentration from the scaffold, subjecting the porous metal scaffold to a vacuum while heating it, flowing an inert gas through or around the porous metal scaffold while heating it, and enhancing a mechanical property of the porous metal scaffold. Heating of the porous metal scaffold can include maintaining a temperature of the scaffold between 1035° C. and 1065° C., inclusive. A system can comprise a reaction chamber, a heater, a gas feed, and a vacuum apparatus. The heater can be configured to heat the reaction chamber and the porous metal scaffold, while the gas feed and the vacuum apparatus respectively flow inert gas and subject the porous metal scaffold to a vacuum.
