Abstract
Some embodiments relate to additive manufactured articles having passivated surfaces and related methods. The methods may comprise forming a three-dimensional (3D) article by additive manufacturing to obtain an additive manufactured 3D article comprising a magnesium component. The method may further comprise exposing the additive manufactured 3D article to a reactive gas phase comprising a fluorine component. The fluorine component from the reactive gas phase may react with the magnesium component of the additive manufactured 3D article to form a passivation layer at and below a surface of the additive manufacture 3D article.

A method for forming an article comprising:
- forming a three-dimensional (3D) article by additive manufacturing to obtain an additive manufactured 3D article, wherein the additive manufactured 3D article comprises a magnesium component;
- and exposing the additive manufactured 3D article to a reactive gas phase to form a passivation layer, wherein the reactive gas phase comprises a fluorine component, wherein the fluorine component reacts with the magnesium component to form magnesium fluoride at and below a surface of the additive manufactured 3D article, and wherein the magnesium fluoride covers at least 90% of gas-exposed surfaces of the additive manufactured 3D article.
