Problems solved by technology

Since the tungsten disulfide film has a graphite-like lamellar structure, low hardness, and is easy to transfer or wear during sliding, it cannot fully meet the lubrication requirements of some special precision instruments. For example, pure and pollution-free solids are required in the field of aerospace precision instruments. Lubricating, no film peeling is allowed; on bearings used in high temperature, high pressure and vacuum environments, film peeling is not allowed, otherwise the peeled debris will adhere to high-voltage parts, and high-pressure sparks will easily occur, causing equipment instability or parts damage

Abstract

A method and device for manufacturing a surface modification layer of a metal material, using an ion implantation method to modify the surface of a metal material with WS2 as a target, the manufacturing method includes pretreatment of the metal material; putting the metal material into a vacuum chamber , using the ion implantation method to generate a surface modification layer of the metal material with WS2 as the target material; the metal material after the surface modification layer is generated is cleaned, dried, and vacuum-sealed. The invention also discloses a metal material surface modification layer manufacturing device used in the manufacturing method. The invention uses ion implantation technology to prepare a tungsten disulfide solid lubricating functional layer on the metal surface, which can significantly reduce the surface friction coefficient of the workpiece without changing the size of the workpiece, and can be used for high temperature, high pressure, high vacuum, high load, high speed, high Lubrication of parts under harsh conditions such as radiation, strong corrosion, and ultra-low temperature.

Description

technical field [0001] The invention relates to the manufacture of a surface modification layer of a metal material, in particular to a method of ion implantation with WS 2 A method and device for manufacturing a surface modification layer of a metal material which is a solid lubricating material. Background technique [0002] Tungsten disulfide (WS 2 ) The preparation method and process research of the modified layer of solid lubricating materials is one of the main research directions in the field of solid lubricating in the world. Tungsten disulfide has a very low coefficient of friction, high extreme pressure resistance, and its oxidation resistance is better than that of the existing solid lubricant MoS 2 Good, so it is suitable for lubrication of parts under severe conditions such as high temperature, high pressure, high vacuum, high load, high speed, high radiation, strong corrosion, and ultra-low temperature. The United States took the lead in applying tungsten di...
