In macroscale manufacturing, active use of heat to alter the geometry, structure and properties of solids is central to material removal, deposition, joining, shaping, and transformation processes. However, traditional heat sources encroach difficulties with fine local selectivity and time exposure control during heating. Therefore, there is an outstanding need for new disruptive heat sources that can enable such performance in nanoscale thermal processing. This presentation describes the fabrication and characterization of “nanoheater” systems based on the exothermic reaction between aluminum and nickel. Various types of nanoheater systems, e.g., multilayers, nanowires, and consolidated particles, have been fabricated and characterized. The spatial and temporal profile of these heat sources can be tailored by altering the structures and dimensions of the nanoheaters. The nanoheaters can be ignited by wired electrical, wireless induction or infrared heating. Consolidated particles were successfully ignited and the reaction self-propagated throughout the compact resulting in the formation of NiAl phase. The ignition characteristics of multilayered structures were investigated by IR thermal camera measurements. These nanoheater sources, which can be either embedded within the volume or on the surface of another material, could revolutionize manufacturing as well as on board thermal actuation and autonomous powering of miniature devices and systems.
