The goals, structure and highlights of a recently completed multiyearmultinational research program are described. The main driving force behind this effort was the aim to advance the technology base so engineers can design, build and operate solid lubricated ceramic tribocomponents in extreme environments. Specially designed friction and wear testers were employed to perform well-defined model experiments on single crystal and polycrystalline ceramics and solid lubricants. The research led to discoveries such as 1 a lubricious oxide with the shear strength of molybdenum disulfide in vacuum, 2 CVD diamond films with low friction and extraordinarily low wear, 3 intercalated graphites with high tribothermal resistance in vacuum and in air, and 4 a wear equation for silicon nitride ceramics.
