Dr. John McCoy
Dr. McCoy is Hi-Z Technology’s Senior Materials Scientist. His current primary focus is on the development of bonding and fabrication technology in support of a NASA JPL initiative to develop a more efficient radioisotope thermoelectric generator for deep space probes. His career specialization has been in the development and analysis of metal/ceramic, metal/carbon, and carbon/ceramic interfaces in the application areas of both aerospace composites and also in electronic packaging. Work in the aerospace composites area included oxidation-resistant coatings for carbon-carbon composites and actively cooled hypersonic airframe skin materials using graphitic foam cores and superalloy face sheets. In the area of thermal management for electronic packaging, he developed low thermal expansion, high thermal conductivity, copper-matrix composites using both graphitic foams and diamond particles for the second phase. He holds one patent on the latter copper/diamond material and a second patent on an integrated metal/ceramic antenna structure. Dr. McCoy received a B.S. in Physics from the College of William & Mary in Virginia, and a Ph.D. in Materials Science from the University of Virginia in Charlottesville.
