Abstract

The invention provides a preparation method of a molybdenum disulfide compound lubricating film for a satellite. The molybdenum disulfide compound lubricating film is prepared by the following steps of: performing closed field unbalanced magnetron sputtering on a MoS2 target, a Ti target and a rare earth fluoride target; and controlling the currents of the MoS2 target and the Ti target and the power of the rare earth fluoride target. The film not only is compact in structure and excellent in antifriction performance, but also improves the wear resistance of a conventional MoS2-based film remarkably, and the service life is prolonged for many times.

Description

technical field [0001] The invention relates to the field of lubricating substance preparation, in particular to a method for preparing a molybdenum disulfide-based composite lubricating film for stars. Background technique [0002] After the spacecraft is launched into orbit, its space environment is very different from the ground atmospheric environment, mainly manifested in: high vacuum, alternating high and low temperature, microgravity, strong radiation and atomic oxygen. Under these special space environmental effects, the traditional space lubricating grease is easy to be volatile, easy to creep, easy to degrade and fail, and can no longer meet the needs of engineering. In particular, the pollutants produced by the volatilization of grease are taboos for optical loads. [0003] MoS 2 Compared with space lubricating grease, solid lubricating coating has the characteristics of zero volatile pollution, high and low temperature resistance, space radiation resistance, an...
