HIGH STRENGTH REFRACTORY ALLOYS
Abstract
The report summarizes the testing of columbium with a zinc coating and columbium plus 2% zirconium with a zinc coating. Both materials were exposed to high temperature exhaust gases supplied from the combustion of various fuels (hydrogen, propane, and JP-4). The maximum temperature to which the zinc coated materials appeared to perform satisfactorily was: (1) less than 1800 degrees F when exposed to the exhaust gas products of hydrogen, and (2) in the region of 2000 to 2200 degrees F when exposed to the exhaust gas products of propane and JP-4 fuels. No advantage would be realized by the use of the materials tested in the turbine section of air breathing gas turbine engines, since the current turbine inlet hot spot temperatures are in the same range as the maximum useful temperature determined for these materials.
