The TiC‐base cermets investigated contained Cr, Fe, Co, Ni, NiAl, ferrosilicon, or Duriron as the metallic constituent. They were evaluated on the basis of strengths at 75° and 1800°F., oxidation resistance at 2000°F., and the degree of chemical reaction between the carbide and metal as determined metallographically. Metallographic and X‐ray studies were conducted on the oxide layers to determine a qualitative mechanism of oxidation. Results of these studies indicated Tic plus NiAl to be the most promising composition and oxygen diffusion to be the governing factor in the oxidation mechanism of all the cermets studied.
