NOVELTY - Manufacturing additive layer involves 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, depositing a carbonaceous coating on the particulate using a product of the decomposed hydrocarbon gas, where the coating has a reflectivity that is lower than a reflectivity the underlying particulate body to reduce an energy input requirement of the particulate to fuse the particulate into a layer of an article using an additive manufacturing technique and receiving coated particulate at an additive manufacturing apparatus, and fusing the coated particulate into a layer of an article using a high density energy source. USE - Method for manufacturing additive layer used for making particulate and particulate feedstock. ADVANTAGE - The method enables to manufacture additive layer with improved electrical, thermal, and/or mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a layer, which comprises particulate body formed from a particulate material and a coating disposed over at least a portion of the particulate body and formed from a carbonaceous material, wherein the coating has a reflectivity that is lower than a reflectivity of the underlying particulate body to reduce an energy input requirement of the particulate to fuse the particulate into a layer of an article using an additive manufacturing technique.
