Typical additive manufacturing processes melt metal powders or beads of metal wire through high intensity directed heat sources to generate successive layers of material in a defined shape forming a 3-D component. Metals can be readily deposited onto 3-dimensional (3-D) substrates from the gaseous state to create a wide range of high-performance shaped components.
We used the carbonyl process for depositing nickel from the gaseous state onto a 3-D polymer-based substrate, which was then easily removed, leaving a net-shape metal part. By controlling the materials of construction in these substrates, along with including other complex geometry as well as potentially embedding heating sources, such that the temporal and spatial temperature distribution would be controlled, we will show that the desired variation in coating thickness and graded composition can be managed successfully, and outline the initial metallographic properties.
