Abstract:
The effect of nuclear radiation on twelve commercial solid film lubricants was determined. The lubricants were typically phenolic or epoxy resin bonded, incorporating graphite or molybdenum disulfide. Gamma exposures covered the range 8.71 x 10exp 9 through 2.61 x 10exp 11 ergs per gram carbon. Neutron exposures were over the range 1 x 10exp 15 to 3 x 10exp 16 nvt fast. Data were obtained on the wear life, corrosion resistance, fluid resistance, and thermal stability. It was observed that radiation, in certain instances, improved wear life rather than decreasing it. Also, those solid films that possessed good corrosion and fluid resistance and good thermal stability prior to irradiation generally were not seriously changed in these properties. Films of poor initial properties were greatly degraded by the radiation. It was concluded that certain of the films should be useable up to the maximum dosages used, but that careful selection would be necessary.
