Abstract:

The fundamental nature of the research was exemplified by ab-initio predictions of the friction coefficient of single crystal diamond sliding against its mating diamond plane, and molecular dynamics calculations on single crystal calcium fluoride and barium fluoride interface shear forces. The test equipment developed for completing the model experiments included an AugerESCA tribometer capable of unidirectional and oscillatory sliding at room temperature, a scanning electron microscope tribometer designed for oscillatory sliding to 1000 C in vacuum and in partial pressures of reactive gases, an 850 C dual-rubshoe friction and wear tester employing a rolling contact fatigue rod as one of the sliding specimens, and 850 C frictiontraction apparatus capable of operating to extraordinarily high PV limits. The fundamental nature of the research notwithstanding, the main goals were directed towards finding potential solutions and applications useful to practicing tribologists and lubrication engineers.
