The extreme temperature adaptability of solid lubricant used in space components was investigated by simulating the temperature environments on the moon surface. The survival adaptability of solid lubricant was estimated through the tests of tensile properties, compressive properties, flexural properties, impact strength, friction and wear properties. Test results indicated that no obvious changs of performances of two typical solid lubricants occurred after 3 moon days storing in the extreme evironments.
