摘要

The overall research program in which this investigation is a part is a study of oxidation of titanium and titanium alloys in hopes of yielding information concerning possible alloy additions which may improve the oxidation resistance of titanium structural materials at temperatures in the range 800 to 1200C. Previous investigations have shown marked improvement in the oxidation resistance of titanium by additions of several metals, of which columbium is one. Because the thermodynamic stability limits for nonstoichiometric rutile is in the range of oxygen chemical potentials which can be conveniently measured by electrochemical techniques, an EMF (electromotive force) cell using yttria doped thoria as a solid electrolyte was designed to determine the thermodynamic properties of nonstoichiometric rutile and rutile containing columbia.
