摘要
Molybdenum disulfide (MoS_2) has been applied to various space mechanisms as solid lubricant. The tribological characteristics of sputtered MoSx films have been improved by inert gas ion implantation. We tried to extend the wear life and reduce friction coefficient by high energy implantation of indium ions. In friction tests, a pin-on-disk tester was used to measure friction coeffi- cient and wear life in a vacuum, dry air and air of 30%, 50% and 80% RH. Indium ions implanted the film at a dose of 1×10^(16) ions/cm^2 exhibited friction coefficient of 0.008 and 5.0 times longer wear life than the unimplanted ones did. However, the wear life of this film tested in high humid air presented no im- provement.
