An investigation of the surface migration of thin films of hydrocarbon oil on metal substrates has been undertaken to determine the effect of temperature gradients on the distribution of lubricants in spacecraft mechanical assemblies. The results of experiments performed in air were discussed earlier. We now discuss the results of experiments performed under vacuum. The important role played by surface finishes is demonstrated. Mathematical models of these results are developed.
