Refractory compounds were selected for investigstion as bearings with the possibility of employing liquid metals as lubricants for these materials. An apparatus designed and built for testing ceramic materials at 2000 deg F in an air atmosphere or liquid metal bath is described. The borides, carbides, nitrides, and silicides of the transition metals and the common oxides which meet the requirements of high-temperature strength, handness, and oxidation resistance were selected for study. Tests to date show that refractory compounds with solid solubility will have poor friction and wear characteristics when tested as couples. Couples of show promise of sliding successfuliy at temperatures as high as 2000 deg F in air. (W.D.M.)
