Abstract: A particulate for an additive manufacturing technique includes a particulate body formed from a particulate material and a coating disposed over particulate body. The coating includes a carbonaceous material that has a reflectivity that is lower than a reflectivity of the particulate material to reduce an energy input requirement of the particulate such that less energy is necessary to fuse the particulate into a layer of an article fabricated using the additive manufacturing technique. A method of making particulate is also disclosed.

Abstract: A method of making a particulate for an additive manufacturing technique includes receiving particulate at a chemical vapor deposition (CVD) reactor, flowing a hydrocarbon gas into the CVD reactor, decomposing the hydrocarbon gas in the CVD reactor, and depositing a carbonaceous coating on the particulate using a product of the decomposed hydrocarbon gas. The coating deposited over the particulate has a reflectivity that is lower than the reflectivity the underlying particulate body to reduce an energy input requirement for purposes of fusing the particulate into a layer of an article using an additive manufacturing technique. In embodiments, the coated particulate can be received at an additive manufacturing apparatus and fused into a layer of an article as a metallic-carbon composite using a high-density energy source.
