Abstract
Coatings processing techniques such as EB-PVD, magnetron sputtering, HiPIMS, electrochemical deposition, and cathodic arc in conjunction with bulk material synthesis via field-assisted sintering technology (FAST) and additive manufacturing (AM) provide the microstructural fidelity needed to tailor and enhance thermomechanical and thermochemical material properties of interest for a variety of applications. Research and development of unique design architectures including monolithic, nano/matrix-composites, nano-layered materials and multi-layer coatings, functionally-graded coatings and bulk ceramics, and nano-grained structural materials have provided the scientific merit required to accelerate the prototyping of next-generation technologies while contributing fundamental science to the broader community. Scientific innovation and advancements towards the development of next-generation technologies spanning energy, defense, medical, transportation, and structural component market sectors have spurred the need for disruptive changes in material performance and processing methodologies. Synthesizing materials and optimizing structure-process-property-performance relationships for corrosion/erosion/ablation resistance, hypersonic vehicles, directed energy weapon systems, optical limiting devices, ultra-hard/ultra-high temperature ceramics, thermal barrier coatings and protection systems, and radiation detection are critical for performance in extreme operating conditions and to supersede the performance of current generation technologies. The Interaction of Ionizing Radiation with Matter (IIRM) University Research Alliance supported through the Defense Threat Reduction Agency (DTRA) has facilitated revolutionary scientific breakthroughs to reduce, eliminate, and counter nuclear and radiological threats. Collaborative efforts include physics, device and system design, and modeling approaches for understanding, identifying, and controlling radiation.
