Abstract
The invention relates to a multi-component composite sulfide solid lubricating film prepared by sulfurizing the surface of a high-entropy alloy. The high-entropy alloy is composed of five metal elements of Co, Cr, Fe, Ni and Mo or six metal elements of Co, Cr, Fe, Ni, Mo and W. The multi-component composite sulfide solid lubricating film of the invention is mainly applied to the friction pair surface of mechanical equipment, the lubricating film and the sulfurized base have high bonding strength, and multi-component composite sulfide solid lubricating films containing different sulfide lubricating phases can be chose and prepared according to the service environment of equipment.
