| abstract |
The present invention relates to a mechanical friction part lubricated by means of a thin film of solid lubricant comprising a compound or a mixture of sulfur-containing metal compounds, fixed on the friction surface (s) of said part and active, in particular, in an inert atmosphere free of oxygen and / or water vapor, characterized in that the film of solid lubricant is substantially exclusively constituted by the compound or the mixture of pure metal compounds, in microcrystalline form. The subject of the invention is also a method for obtaining said mechanical part. Application: Lubrication in an atmosphere free of oxygen and / or water, for example in space, in vacuum, etc. (mechanical, micromechanical). |
