Abstract : A basic test facility for performing compression, tension, torsion, cohesion, adhesion, and sliding experiments on cylindrically shaped molybdenum disulfide (MoS2) specimens in a controlled atmosphere or in vacuum was designed, fabricated, and put into operation. Compacts of a reference MoS2 powder and a commercially available MoS2 powder were made, without the use of a binder, over a wide range of compacting pressures and length-to-diameter ratios. Data were obtained on the variations of compact specific gravity and hardness with respect to compacting pressure and length-to-diameter ratio. Measurements were also made on the compressive and tensile properties of the MoS2 specimens in clean dry air and at room temperature. The ultimate compressive and tensile strength were determined over a wide range of specimen specific gravities, as were the moduli of elasticity in compression and tension. (Author)
