Isothermal experiments were performed on TaC‐coated carbon‐carbon in flowing hydrogen at atmospheric pressure. Considerable effort was put into trying to detect an enhanced rate of erosion at intermediate temperatures (∼1400 K) as was found in the NERVA program. No such enhancement (‘‘midband corrosion’’) was observed, and the temperature dependence of the reaction rates seemed to follow simple activated behavior consistent with a single rate‐limiting process.
