Dr. Kaplowitz’s areas of expertise include failure analysis, metallurgy, fracture, and materials characterization. He specializes in metallic coatings, dimensional repair, powder process development (nano and micro), metals additive manufacturing, and nanothermite processing. Dr. Kaplowitz has extensive experience performing mechanical testing as well as microstructural analysis via optical microscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and energy dispersive X-ray spectroscopy (EDX).
Prior to joining Exponent, Dr. Kaplowitz was a postdoctoral researcher at the U.S. Army Research Laboratory Center for Cold Spray where he managed cold spray dimensional repair and additive manufacturing testing programs for clients, including the private sector, defense contractors, and divisions of the U.S. Army, Navy, and Air Force. Dr. Kaplowitz planned and performed equipment operation for novel cold/thermal spray research with a wide range of metal, ceramic, and composite powder and substrate combinations. For these investigations, he characterized deposit quality and performance with metallurgical analyses, SEM, optical microscopy, and mechanical testing.
During his graduate study at the University of Maryland, Dr. Kaplowitz researched small-scale nanothermite production using mass flow controlled aerosol systems. His work focused on characterization of synthesized aluminum nanopowder and thermite combinations with SEM, TEM, XPS, TGA, combustion chamber testing, and temperature-jump wire ignition. He invented and patented a scalable process for continuous production of nanoaluminum, improving efficiency and reducing costs compared to current batch-based systems. He subsequently developed thin film coated nanoaluminum products that increased aluminum fuel content and decreased required ignition temperature.
