Tungsten-based composites with a variety of second-phase additions were fabricated and tested in a hyperthermal electric arc under conditions simulating hypersonic flight. Composites consisting of porous tungsten matrix infiltrated with Cu/Zr or Ag/Zr alloys demonstrated excellent oxidation resistance as compared to pure tungsten, graphite, or disilicide-coated tungsten. Analysis of hypersonic environments, composite fabrication, and test procedures and results are described in this report. (Author)
